The Siemens 5SU1354-1RC10 is a SENTRON / Betagard 5SU1 Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide combined overload, short-circuit and residual-current protection in one compact device. The exact product specification identifies it as a 10 A, 2-pole / 1P+N, 2-module, C-characteristic, Type AC, 30 mA RCBO for compatible single-phase electrical circuits.
The product is intended for applications requiring both circuit overcurrent protection and residual-current protection in a compact modular device. The supplied Siemens designation also states that the product is permitted in all countries, subject to applicable national installation regulations.
The 5SU1354-1RC10 belongs to the Siemens SENTRON / Betagard 5SU1 RCBO family.
Unlike a conventional RCCB, an RCBO combines:
Overload protection
Short-circuit protection
Residual-current protection
in a single device.
This integrated construction can simplify electrical-panel design and provide dedicated protection to individual circuits without requiring separate MCB and RCCB devices.
The RCBO has a rated current of 10 A.
This makes it suitable for compatible single-phase circuits designed around a 10 A protective device.
Typical circuit applications can include:
Lighting circuits
Control circuits
Instrumentation circuits
Small electronic equipment
Building auxiliary circuits
Automation control circuits
Small single-phase equipment
The final current rating should always be selected according to the connected load, conductor capacity, installation method and applicable regulations.
The 5SU1354-1RC10 uses a C tripping characteristic.
The C curve is intended for compatible circuits where normal operation may involve moderate starting or inrush current.
Potential applications include:
Small motors
Fans
Pumps
Contactors
Solenoids
Control transformers
Selected lighting equipment
Industrial auxiliary loads
The C characteristic should be matched to the actual load and protection-coordination requirements.
The device uses Type AC residual-current protection.
Type AC protection is designed for compatible sinusoidal alternating residual currents.
Before selecting Type AC, the residual-current waveform of the connected equipment should be considered. Equipment that can produce pulsating DC or other residual-current components may require a different residual-current protection type.
The 5SU1354-1RC10 has a rated residual operating current of 30 mA.
When the residual-current condition reaches the specified operating threshold, the RCBO disconnects the protected circuit.
The 30 mA sensitivity should be selected according to the complete electrical protection design and applicable installation requirements.
This model should not automatically be substituted with a 100 mA or 300 mA device because those have different residual-current operating thresholds.
The device has 2 poles in a 1P+N configuration.
This arrangement is suitable for compatible single-phase circuits where phase and neutral are incorporated into the switching and protection arrangement.
Typical applications include:
Single-phase distribution boards
Commercial electrical panels
Office circuits
Building electrical systems
Equipment feeders
Industrial auxiliary circuits
Control-panel supplies
The 5SU1354-1RC10 is intended for compatible single-phase AC applications in the 240 V AC class.
The actual installation voltage should always be checked against the exact Siemens technical documentation and the electrical-system design.
The RCBO incorporates short-circuit protection as part of its overcurrent function.
The short-circuit capability should be checked against the prospective fault current at the installation point and the applicable Siemens product rating.
This allows the RCBO to provide both circuit overcurrent and residual-current protection in a single compact unit.
A conventional circuit arrangement may require:
MCB + RCCB
The RCBO combines the relevant functions:
RCBO = Overload + Short Circuit + Residual Current Protection
This can reduce component count and simplify circuit-level protection in electrical distribution boards.
The 5SU1354-1RC10 is specified as a 2-module device.
A 2-module modular format occupies approximately 36 mm of standard panel width.
This compact construction is useful for:
DIN-rail distribution boards
Commercial electrical panels
Control panels
Sub-distribution boards
Industrial electrical enclosures
The 2-module designation refers to physical panel space and does not represent a power rating.
The Siemens 5SU1 RCBO family is designed for modular electrical installation.
The 5SU1354-1RC10 can be integrated into suitable DIN-rail distribution boards and electrical panels alongside compatible protective and control components.
Installation should follow Siemens' product instructions, wiring requirements and applicable national regulations.
The overcurrent section of the RCBO protects the connected circuit against sustained excessive current caused by overload.
The 10 A rating should be coordinated with:
Cable ampacity
Connected load
Installation method
Ambient conditions
Protection requirements
Correct coordination helps protect the circuit while minimizing nuisance tripping.
The RCBO's overcurrent section also provides protection against short-circuit conditions.
The prospective short-circuit current at the installation point should be checked against the product's specified breaking capacity and the complete protection arrangement.
Residual current occurs when part of the electrical current flows outside its intended path, such as through an unintended leakage path to earth.
The RCBO monitors the relevant condition and disconnects the protected circuit when the residual-current threshold reaches 30 mA.
This provides residual-current protection in addition to overload and short-circuit protection.
The C characteristic can be useful for compatible loads that experience moderate inrush current.
Potential applications include:
Small pumps
Fans
Small motors
Solenoids
Contactors
Control transformers
Industrial auxiliary equipment
Selected commercial loads
The actual selection should be based on the load's starting characteristics and protection coordination.
The 5SU1354-1RC10 is intended for compatible sinusoidal AC residual currents.
For modern electronic equipment with rectifiers, variable-speed drives or other power-electronic circuits, the required residual-current type should be verified before choosing Type AC.
The 5SU1354-1RC10 can be considered for compatible:
Lighting circuits
Control circuits
Instrumentation circuits
Commercial distribution boards
Office electrical systems
Building auxiliary circuits
Automation panels
Small equipment feeders
The final application should follow the electrical-system design and applicable standards.
A typical circuit arrangement can be:
Incoming Supply → RCBO → Protected Single-Phase Load
The overall protection design should consider:
Prospective short-circuit current
Cable capacity
Load current
C-curve characteristics
30 mA residual-current sensitivity
Upstream protection
Applicable national installation regulations
The Siemens 5SU1 design allows flexible panel wiring according to the relevant product configuration and installation instructions.
The exact wiring arrangement should always be checked against the manufacturer's terminal and connection diagram before installation.
The RCBO should be installed inside a suitable distribution board or electrical enclosure to provide the required environmental and touch protection.
The protection degree depends on the completed installation and enclosure arrangement.
The device should be installed within the manufacturer's specified ambient conditions.
Electrical-panel designers should consider:
Ambient temperature
Humidity
Ventilation
Enclosure conditions
Installation altitude
Applicable derating requirements
These factors can affect protective-device performance.
The supplied Siemens product description states that the 5SU1354-1RC10 is permitted in all countries and specifically instructs users to observe national installation regulations.
For installations in India, the applicable Indian electrical installation requirements and Siemens installation instructions should be followed.
