Product Description

Siemens 5SV4312-0RC RCCB – 25A, 2-Pole, 30mA, Type AC, 240V

The Siemens 5SV4312-0RC is a SENTRON 5SV4 Residual Current Operated Circuit Breaker (RCCB) designed for residual-current protection in suitable single-phase AC electrical installations. It features a 25 A rated current, 2-pole / 1+N configuration, 30 mA rated residual operating current, and Type AC residual-current protection. The corresponding Siemens 5SV4312-0 is an instantaneous Type AC RCCB for 1P+N applications and is intended for modular electrical distribution systems.

The India product designation specifies 240 V, 2MW, making this model suitable for compatible single-phase distribution boards, electrical panels, feeder circuits and modular protection assemblies.

Siemens 5SV4312-0RC Residual Current Circuit Breaker

The 5SV4312-0RC belongs to the Siemens SENTRON 5SV4 / Betagard RCCB family. Its primary purpose is to detect residual current in the protected circuit and disconnect the circuit when the residual current reaches the specified operating threshold.

The 2-pole / 1+N configuration is designed for suitable single-phase circuits where phase and neutral are incorporated into the residual-current protection arrangement.

25 A Rated Current

The RCCB has a rated current of 25 A.

This makes it suitable for compatible single-phase distribution circuits and feeders where a 25 A residual-current protection device is required.

The protected circuit should be designed so that the RCCB remains within its specified current, voltage and environmental operating conditions.

30 mA Residual Current Sensitivity

The 5SV4312-0RC has a rated residual operating current of 30 mA.

When residual current reaches the specified operating threshold, the RCCB trips and disconnects the protected circuit.

The 30 mA sensitivity should be selected according to the complete electrical protection design and applicable installation requirements.

Type AC Residual Current Protection

This model is a Type AC RCCB.

Type AC residual-current circuit breakers are designed for compatible sinusoidal alternating residual currents. The appropriate RCCB type should always be selected according to the residual-current waveform expected in the actual application.

2-Pole / 1+N Configuration

The 5SV4312-0RC has 2 poles and is intended for 1+N single-phase applications.

This arrangement allows the phase and neutral conductors to be incorporated into the residual-current protection system.

Typical applications include:

• Single-phase distribution boards

• Commercial electrical panels

• Building electrical installations

• Equipment feeders

• Sub-distribution circuits

• Office electrical systems

• Industrial auxiliary circuits

240 V AC / 230 V AC Application

The supplied India product designation identifies the device as a 240 V, 2-module RCCB.

For Siemens 5SV4 Type AC 1P+N devices in this range, the rated operating voltage is specified in the 230 V AC class for the corresponding international product data. The actual installation voltage should be checked against the current Siemens product documentation and the electrical system design.

Instantaneous Operation

The 5SV4312-0RC belongs to the Siemens instantaneous Type AC 1P+N RCCB range.

Instantaneous operation means the device responds without an intentionally introduced short-time delay when the specified residual-current threshold is reached.

This can provide rapid interruption of the protected circuit when the residual-current operating level is exceeded.

Short-Circuit Coordination

An RCCB primarily provides residual-current protection and should be coordinated with appropriate upstream overcurrent protection such as an MCB or MCCB where required.

The overall protection arrangement should consider:

• Prospective short-circuit current

• Upstream overcurrent device

• Rated current

• Conductor size

• System voltage

• Installation requirements

The RCCB should not be treated as a substitute for an overcurrent protective device unless the complete protection scheme specifically provides that function.

Compact 2-Module Design

The India product description specifies 2MW, meaning 2 module width.

The 2MW designation refers to the physical modular width of the device and does not indicate a 2 MW power rating.

The compact format is suitable for:

• Modular distribution boards

• Consumer units

• Commercial electrical panels

• Sub-distribution boards

• Compact electrical enclosures

DIN Modular Installation

The 5SV4312-0RC is designed for modular installation in suitable electrical distribution assemblies.

Its compact 1P+N form factor allows it to be integrated with compatible MCBs, busbars and other protection accessories according to the panel design.

This makes it convenient for panel builders working with standard modular protection systems.

Residual Current Protection

Residual current can occur when a portion of electrical current flows through an unintended path, such as leakage to earth.

The RCCB monitors the relevant current balance and disconnects the protected circuit when the residual current reaches the configured 30 mA threshold.

This provides an additional layer of residual-current protection within the complete electrical protection system.

Single-Phase Distribution Applications

The 5SV4312-0RC can be considered for compatible single-phase applications such as:

• Residential distribution boards

• Commercial panels

• Building electrical systems

• Office distribution circuits

• Equipment supply circuits

• Single-phase feeder protection

• Industrial auxiliary circuits

The actual application should be determined according to the electrical protection design and applicable regulations.

Protection Coordination

A typical protection arrangement can include:

Incoming Supply → MCB/MCCB → RCCB → Protected Load

The exact arrangement depends on the system design and required overcurrent and residual-current protection functions.

Proper coordination helps ensure that the RCCB performs its intended residual-current protection role.

Maintenance and Testing

RCCBs should be included in an appropriate electrical inspection and testing program.

The device test function should be operated according to the manufacturer's instructions and applicable maintenance requirements to verify correct tripping.

Regular testing helps confirm that the residual-current protection mechanism remains operational.

Installation Considerations

Before selecting the 5SV4312-0RC, verify:

• Rated current: 25 A

• Residual-current sensitivity: 30 mA

• RCCB type: Type AC

• Pole arrangement: 2-pole / 1+N

• System voltage compatibility

• Upstream overcurrent protection

• Available panel space: 2 module width

• Conductor size and termination

• Applicable national electrical regulations

The correct RCCB type and residual-current sensitivity should always be selected according to the actual installation.

The 5SV4314-0RC is the corresponding 40 A, 2-pole / 1+N, 30 mA, Type AC RCCB.

Therefore:

5SV4312-0RC → 25 A, 30 mA

5SV4314-0RC → 40 A, 30 mA

The main difference is the rated current.

Difference from 63 A Version

Therefore:

5SV4312-0RC → 25 A

5SV4314-0RC → 40 A

5SV4316-0RC → 63 A

The correct rated current should be selected according to the protected circuit.

Difference from 80 A Version

The 5SV4317-0 belongs to the corresponding 80 A, 2-pole / 1+N, Type AC, 30 mA family.

Therefore:

5SV4312-0RC → 25 A

5SV4314-0RC → 40 A

5SV4316-0RC → 63 A

5SV4317-0RC → 80 A

These devices share the basic Type AC, 1P+N and 30 mA configuration while differing in rated current.

Difference from 100 mA Version

The 5SV4412-0RC is the corresponding 25 A, 2-pole / 1+N, Type AC, 100 mA version.

Therefore:

5SV4312-0RC → 25 A, 30 mA

5SV4412-0RC → 25 A, 100 mA

The main difference is the residual-current operating threshold.

Difference from 300 mA Version

The 5SV4612-0RC is the corresponding 25 A, 2-pole / 1+N, Type AC, 300 mA version.

Therefore:

5SV4312-0RC → 25 A, 30 mA

5SV4412-0RC → 25 A, 100 mA

5SV4612-0RC → 25 A, 300 mA

The appropriate sensitivity should be selected according to the electrical protection design.

Difference from 4-Pole Version

The 5SV4342-0RC is the corresponding 25 A, 4-pole / 3+N, Type AC, 30 mA RCCB, while the 5SV4312-0RC is a 2-pole / 1+N device.

Therefore:

5SV4312-0RC → 25 A, 2-pole / 1+N, 30 mA

5SV4342-0RC → 25 A, 4-pole / 3+N, 30 mA

The first is intended for suitable single-phase systems and the second for suitable three-phase-plus-neutral systems.
