The product designation supplied for the SB Smart listing is 5SU1654-7RC16, with a 2-pole, 2-module, C-characteristic, Type A, 300 mA configuration.

Siemens 5SU1654-7RC16 RCBO

The 5SU1654-7RC16 belongs to the Siemens SENTRON / Betagard 5SU1 RCBO family. Unlike an RCCB, which primarily provides residual-current protection, an RCBO combines:

• Overload protection

• Short-circuit protection

• Residual-current protection

in one device.

This integrated arrangement can simplify electrical-panel design and reduce the requirement for separate MCB and RCCB devices.

Siemens' 5SU1 catalogue identifies the 16 A, Type A, 300 mA, C-characteristic configuration within this RCBO family.

16 A Rated Current

The device is rated at 16 A.

This makes it suitable for compatible single-phase circuits where the connected load and conductor system are designed for a 16 A protective device.

Typical applications can include:

• Lighting circuits

• Socket circuits

• Control circuits

• Small equipment feeders

• Electronic equipment

• Building auxiliary circuits

• Industrial auxiliary loads

The final current rating must be selected according to the cable, load, installation method and applicable electrical regulations.

C Tripping Characteristic

The RCBO uses a C tripping characteristic.

A C-curve device is suitable for circuits where normal operation can involve moderate starting or inrush currents.

Potential applications include:

• Small motors

• Pumps

• Fans

• Contactors and solenoids

• Control transformers

• Certain lighting circuits

• Electronic equipment with moderate inrush current

The C characteristic should be selected according to the actual load and protection-coordination requirements.

Type A Residual Current Protection

The 5SU1654-7RC16 is specified as a Type A RCBO.

Type A residual-current protection is designed to detect suitable AC residual currents as well as pulsating DC residual-current components.

This makes Type A protection suitable for many modern electrical installations containing:

• Electronic power supplies

• Rectifier circuits

• Automation equipment

• Variable-speed equipment

• Modern appliances

• Industrial control electronics

The correct residual-current type should always be selected according to the equipment and its possible leakage-current waveform. Siemens' current technical data identifies the corresponding 16 A device as Type A.

300 mA Residual Current Sensitivity

The specified residual operating current is 300 mA.

When the residual-current level reaches the applicable operating threshold, the residual-current protection function disconnects the circuit.

The 300 mA sensitivity should be selected according to the overall electrical protection design. It should not be automatically substituted with a 30 mA device because the two serve different protection requirements.

Siemens' current data for the corresponding 5SU1654-7KK16 explicitly specifies 300 mA residual-current sensitivity.

2-Pole / 1+N Configuration

The device is a 2-pole / 1+N RCBO.

This configuration is intended for compatible single-phase circuits in which phase and neutral are included in the switching arrangement.

Typical applications include:

• Single-phase distribution boards

• Commercial panels

• Building electrical systems

• Office circuits

• Equipment feeders

• Industrial auxiliary circuits

• Control-panel supplies

230 V AC Technical Rating

Siemens' current technical data for the corresponding 5SU1654-7KK16 specifies a 230 V AC rated operating voltage.

For an India product listing, the device may be marketed for the corresponding single-phase supply category, but the actual installation voltage should always be checked against the exact Siemens article and system design.

10 kA Short-Circuit Rating

The corresponding Siemens 5SU1654-7KK16 is specified as a 10 kA RCBO.

This provides a high short-circuit interrupting capability within the specified application conditions.

The RCBO should still be coordinated with the prospective short-circuit current and upstream protection arrangement of the installation.

Combined Overcurrent and Residual-Current Protection

A major advantage of the 5SU1654-7RC16 is its combined protection architecture.

A conventional arrangement may use:

MCB + RCCB

The RCBO combines those protective functions:

RCBO = Overload + Short Circuit + Residual Current Protection

This can reduce component count and simplify circuit-level protection.

Compact Modular Installation

The product is identified as a 2-module RCBO configuration.

The compact format is suitable for:

• DIN-rail distribution boards

• Consumer units

• Commercial electrical panels

• Control panels

• Sub-distribution boards

• Industrial electrical enclosures

The Siemens 5SU1 Type A 1P+N catalogue range identifies these devices in compact modular configurations.

DIN-Rail Applications

The 5SU1 RCBO family is intended for modular electrical distribution installations.

The compact construction allows the device to be installed alongside other DIN-mounted protection and control components according to the panel design.

This is useful for panel builders and electrical contractors working with compact modular protection systems.

Overload Protection

The overcurrent section of the RCBO provides protection against excessive current caused by circuit overload.

The 16 A rated current should be coordinated with the cable size and connected load so the protective device can provide the intended circuit protection.

Short-Circuit Protection

The RCBO also provides protection against short-circuit conditions.

The 10 kA rating of the corresponding Siemens device should be considered against the prospective fault current at the installation point.

The complete protection system should always be designed according to applicable standards and installation requirements.

Residual-Current Protection

The residual-current section detects current imbalance associated with unwanted leakage paths.

When the residual-current operating condition is reached, the RCBO disconnects the protected circuit.

This allows the device to combine residual-current protection with conventional overcurrent protection in one compact unit.

Applications with Electronic Loads

The Type A characteristic makes the device suitable for compatible applications where residual currents may contain pulsating DC components.

Potential applications include:

• Electronic control panels

• Automation systems

• Switching power supplies

• Rectifier-based equipment

• Industrial electronics

• Modern commercial equipment

The actual suitability should be verified against the leakage-current characteristics of the connected equipment.

C-Curve Applications

The C characteristic can be useful for loads with moderate inrush current.

Suitable applications may include:

• Small motors

• Pumps

• Fans

• Transformers

• Solenoids

• Certain lighting systems

• Equipment with startup current

The actual trip characteristic should be selected based on load behavior and coordination requirements.

Industrial and Commercial Applications

The 5SU1654-7RC16 can be considered for:

• Industrial control circuits

• Machine auxiliary circuits

• Commercial distribution boards

• Building electrical systems

• Office equipment circuits

• Small equipment feeders

• Automation panels

• Single-phase electrical outlets

The final application should follow the electrical design and relevant local standards.

Difference Between RCBO and RCCB

The 5SU1654-7RC16 is an RCBO, whereas the Siemens 5SV-series products in the previous listings are primarily RCCBs.

An RCCB primarily provides residual-current protection and normally needs separate overcurrent protection.

An RCBO combines:

Residual-current protection + overload protection + short-circuit protection

This makes RCBOs useful for individual circuit protection.

Difference from 5SU1654-7RC32

The 5SU1654-7RC32 is the higher-current 32 A version in the same Type A, 300 mA, C-characteristic family.

Therefore:

5SU1654-7RC16 → 16 A

5SU1654-7RC32 → 32 A

The main difference is the rated current.

Difference from 25 A Version

The Siemens 5SU1 Type A, 300 mA, C-characteristic range also includes 25 A variants.

The 5SU1654-7RC16 should be selected where the protected circuit requires a 16 A rated current.

Difference from 40 A Version

Higher-current RCBO variants such as 40 A are available in the 5SU1 family, but the exact residual-current type and characteristic should be verified before substitution.

The 5SU1654-7RC16 is specifically the 16 A, C-characteristic, Type A, 300 mA configuration.

Difference from 30 mA Type A RCBO

The 5SU1 family also includes Type A RCBOs with 30 mA residual-current sensitivity.

The 5SU1654-7RC16 configuration is specifically 300 mA.

Therefore, a 30 mA Type A RCBO should not be treated as a direct replacement without confirming the protection requirement of the circuit.
