Product Description

Siemens 5SV4612-0RC RCCB – 25A, 2-Pole, 300mA, Type AC, 240V

The Siemens 5SV4612-0RC is a SENTRON 5SV4 residual current operated circuit breaker (RCCB) designed for single-phase AC electrical networks requiring residual-current protection. It is a 2-pole / 1+N RCCB with a 25 A rated current, 300 mA residual operating current, and Type AC residual-current characteristic. Siemens lists the device as an instantaneous RCCB with a 10 kA short-circuit current rating and 240/415 V AC supply range.

Siemens 5SV4612-0RC Residual Current Circuit Breaker

The 5SV4612-0RC belongs to the Siemens SENTRON 5SV4 RCCB family. Its main function is to disconnect the protected circuit when a residual current reaches the specified operating threshold.

The 2-pole configuration is intended for 1-phase + neutral (1+N) installations, making it suitable for residential, commercial and compatible industrial single-phase circuits. Siemens' 2025 residual-current protection catalogue lists the 25 A, 300 mA article within the Type AC, 1P+N, 2-module range.

25 A Rated Current

The RCCB has a rated current of 25 A.

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

The complete circuit should be designed so that the RCCB is operated within its specified voltage, current and installation conditions.

300 mA Residual Current Sensitivity

The 5SV4612-0RC has a rated residual operating current of 300 mA.

When the residual current reaches the specified trip threshold, the device disconnects the protected circuit.

The correct residual-current sensitivity should be selected according to the electrical protection design and applicable installation requirements.

Type AC Residual Current Protection

This model is a Type AC RCCB.

Type AC RCCBs are intended for sinusoidal AC residual currents. The appropriate RCCB type should be selected according to the waveform of residual current that may occur in the actual application.

2-Pole / 1+N Configuration

The device has 2 poles and is intended for 1+N single-phase circuits.

This arrangement allows the phase and neutral conductors to be incorporated into the RCCB switching arrangement.

Typical applications include:

• Single-phase distribution boards

• Residential circuits

• Commercial electrical panels

• Small industrial feeders

• Control circuits

• Equipment supply circuits

• Sub-distribution systems

240 V AC Application

The India-facing product description identifies the device as a 240 V, 2-module RCCB. Siemens' current technical data specifies a 240/415 V AC supply-voltage range for the article family, with the 1+N device intended for the appropriate single-phase application.

The actual system voltage should be verified against the installation requirements before selection.

Instantaneous Operation

The 5SV4612-0RC is specified as an instantaneous residual-current circuit breaker.

Siemens states that the device does not have a short-time delayed switching function.

This allows the RCCB to respond without an intentional delay when the residual-current threshold is reached.

10 kA Short-Circuit Current Rating

The device is specified with a 10 kA short-circuit current rating.

The RCCB should still be coordinated with appropriate upstream overcurrent protection and the prospective short-circuit conditions of the electrical installation.

An RCCB provides residual-current protection and should not be treated as a substitute for an overcurrent protective device unless the complete protection scheme specifically provides the required function.

Rated Insulation Voltage

The 5SV4612-0RC has a specified rated insulation voltage of 2,000 V.

This is an important insulation characteristic when integrating the RCCB into the electrical distribution system.

DIN 43880 Modular Design

Siemens identifies the device as size 1 according to DIN 43880, corresponding to a compact modular installation format.

For the India product description, the article is specified as 2MW, or 2 module width, making it suitable for compact distribution boards and modular electrical panels.

60 mm Grid Spacing

The Siemens data sheet specifies a 60 mm grid spacing for the device.

This supports integration into conventional modular distribution-board arrangements.

IP20 Protection

Siemens specifies IP20 protection when the device is installed in a suitable distribution board with connected conductors.

The RCCB should therefore be installed inside an appropriate enclosure or distribution assembly.

Residual Current Protection

A residual current occurs when some current flows through an unintended path, such as leakage to earth.

The RCCB continuously monitors the relevant current balance and trips when the residual current reaches the configured 300 mA operating threshold.

This provides a layer of protection against persistent earth-leakage conditions in the protected circuit.

Single-Phase Distribution Applications

The 5SV4612-0RC is suitable for compatible single-phase + neutral circuits such as:

• Distribution boards

• Small power circuits

• Commercial installations

• Residential electrical systems

• Office electrical circuits

• Lighting or equipment feeders

• Compatible industrial auxiliary circuits

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

Modular Panel Installation

The compact 2-module form factor makes the device suitable for:

• Consumer distribution boards

• Commercial panels

• Sub-distribution boards

• Control panels

• Small electrical enclosures

• Modular protection assemblies

Its compact design can help optimize available panel space.

Maintenance and Testing

Residual-current circuit breakers should be included in an appropriate inspection and testing program.

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

Installation Considerations

Before selecting the 5SV4612-0RC, verify:

• Rated current: 25 A

• Residual-current sensitivity: 300 mA

• RCCB type: Type AC

• Pole arrangement: 2-pole / 1+N

• System voltage compatibility

• Upstream overcurrent protection

• Available panel space

• Applicable national installation regulations

Siemens notes that use of these devices is not permitted in all countries and that national installation regulations must be observed.

Difference from 30 mA Version

The 5SV4312-0RC belongs to the same general 25 A, 2-pole Type AC family but uses a 30 mA residual-current sensitivity, whereas 5SV4612-0RC uses 300 mA.

Therefore:

5SV4312-0RC → 30 mA

5SV4612-0RC → 300 mA

The correct sensitivity should be selected according to the intended protection scheme. Siemens' 2025 catalogue lists both sensitivity classes within the Type AC 1P+N family.

Difference from 100 mA Version

The 5SV4412-0 is the corresponding 25 A, 2-pole Type AC, 100 mA version, while 5SV4612-0 is the 300 mA version. Siemens' selection table distinguishes the variants by residual operating current.

Difference from 4-Pole Version

The 5SV4642-0RC is a 25 A, 4-pole / 3+N, 300 mA, Type AC RCCB for three-phase plus neutral systems. The 5SV4612-0RC is the 2-pole / 1+N single-phase version. Siemens India lists the 4-pole article separately.

Therefore:

5SV4612-0RC → 25 A, 2-pole, 1+N

5SV4642-0RC → 25 A, 4-pole, 3+N

Difference from 40 A Version

For installations requiring a higher current rating, Siemens offers other 5SV4 variants such as 40 A Type AC RCCBs.

The 5SV4612-0RC should be selected specifically where the circuit requires a 25 A rated RCCB.
