Product Description

Siemens 5SV4342-0RC RCCB – 25A, 4-Pole, 30mA, Type AC, 415V

The Siemens 5SV4342-0RC is a SENTRON 5SV4 Residual Current Operated Circuit Breaker (RCCB) designed for residual-current protection in suitable three-phase AC electrical installations with neutral. It is a 4-pole / 3+N, Type AC RCCB with a 25 A rated current and 30 mA rated residual operating current. The Siemens product data identifies the corresponding 5SV4342-0 as an instantaneous 4-pole Type AC RCCB, while the India market designation specifies 415 V and 4-module width.

Siemens 5SV4342-0RC Residual Current Circuit Breaker

The 5SV4342-0RC belongs to the Siemens SENTRON 5SV4 RCCB family. Its primary function is to detect residual current and disconnect the protected circuit when the residual current reaches the specified operating threshold.

The 4-pole / 3+N configuration is intended for three-phase systems with neutral, making the device suitable for compatible industrial, commercial and building distribution applications. Siemens lists the corresponding product as a 4-pole, Type AC, 25 A, 30 mA RCCB.

25 A Rated Current

The 5SV4342-0RC has a rated current of 25 A.

This makes it suitable for compatible three-phase circuits and feeders where a 25 A residual-current protection device is required. The complete electrical installation should be designed so that the RCCB remains within its specified electrical ratings and operating conditions.

30 mA Residual Current Sensitivity

The device has a rated residual operating current of 30 mA. Siemens' technical data identifies the 5SV4342-0 article with a 30 mA tripping fault current.

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 actual protection design, installation requirements and applicable electrical regulations.

Type AC Residual Current Protection

The 5SV4342-0RC is a Type AC RCCB.

Type AC residual-current devices are intended for compatible sinusoidal alternating residual currents. The RCCB type should be selected according to the leakage-current waveform that can occur in the actual electrical installation.

4-Pole / 3+N Configuration

The device has 4 poles, suitable for three-phase plus neutral circuits.

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

Typical applications include:

• Three-phase distribution boards

• Industrial feeder circuits

• PCC panels

• MCC panels

• Commercial electrical panels

• Sub-distribution boards

• Machine supply circuits

• Factory electrical systems

415 V AC India Application

The supplied India product description identifies this article as a 415 V, 4-module RCCB. Indian product data also identifies the exact model as 25 A, 4-pole, 30 mA, Type AC, 415 V AC.

Siemens' international product data for the corresponding 5SV4342-0 specifies 400 V AC.

For the SB Smart product page, the 415 V India-market designation can therefore be retained while the actual installation should be checked against the Siemens-rated system voltage and the electrical design.

Instantaneous Operation

The 5SV4342-0RC is an instantaneous RCCB. Siemens documentation identifies the corresponding 5SV4342-0 as instantaneous and confirms that the switching function is not short-time delayed.

This means the device operates without an intentionally introduced short-time delay when the residual-current threshold is reached.

Short-Circuit Coordination

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

The complete protection arrangement should consider:

• Prospective short-circuit current

• Upstream protective device

• Rated current

• Conductor size

• Installation conditions

• Applicable electrical standards

Siemens' technical data for the corresponding 5SV4342-0 specifies a 10 kA short-circuit current rating.

4-Module Design

The India product description specifies 4MW, meaning 4 module width.

The 4MW designation refers to the physical modular width and does not mean a 4 MW power rating.

This makes the RCCB suitable for:

• Modular distribution boards

• Electrical control panels

• PCC panels

• Sub-distribution boards

• Commercial switchboards

• Industrial protection assemblies

DIN Modular Installation

The 5SV4342-0RC is designed for modular electrical distribution installation.

Its compact modular construction allows it to be installed alongside compatible MCBs, busbars and other protection accessories according to the panel design.

Siemens technical data specifies 60 mm grid spacing for the corresponding 5SV4342-0 device.

Residual Current Protection

Residual current occurs when part of the 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 30 mA operating threshold.

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

Three-Phase Distribution Applications

The 5SV4342-0RC can be considered for compatible:

• Industrial distribution boards

• Commercial electrical panels

• Three-phase feeder circuits

• PCC and MCC panels

• Factory electrical systems

• Building distribution systems

• Machine supply circuits

• Sub-distribution boards

Industrial Panel Applications

The combination of:

25 A + 30 mA + Type AC + 4-pole / 3+N

makes this article suitable for selected three-phase residual-current protection applications.

Panel builders can use the device where the electrical protection design specifically calls for a 30 mA Type AC RCCB with a 25 A rated current.

Maintenance and Testing

RCCBs should be included in the electrical installation's routine inspection and testing program.

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

Regular testing helps confirm that the protection mechanism remains operational.

Installation Considerations

Before selecting the 5SV4342-0RC, verify:

• Rated current: 25 A

• Residual-current sensitivity: 30 mA

• RCCB type: Type AC

• Pole configuration: 4-pole / 3+N

• System voltage compatibility

• Upstream overcurrent protection

• Available panel space: 4 module width

• Conductor size and termination

• Applicable national electrical regulations

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

Difference from 40 A Version

The 5SV4344-0RC is the corresponding 40 A, 4-pole, Type AC, 30 mA version.

Therefore:

5SV4342-0RC → 25 A, 30 mA

5SV4344-0RC → 40 A, 30 mA

The primary difference is the rated current.

Difference from 63 A Version

The 5SV4346-0RC is the corresponding 63 A, 4-pole, Type AC, 30 mA version.

Therefore:

5SV4342-0RC → 25 A

5SV4344-0RC → 40 A

5SV4346-0RC → 63 A

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

Difference from 80 A Version

The 5SV4347-0RC is the corresponding 80 A, 4-pole, Type AC, 30 mA version.

Therefore:

5SV4342-0RC → 25 A

5SV4344-0RC → 40 A

5SV4346-0RC → 63 A

5SV4347-0RC → 80 A

These models share the same basic Type AC, 4-pole, 30 mA configuration but have different current ratings.

Difference from 100 mA Version

The 5SV4442-0RC is the corresponding 25 A, 4-pole, Type AC, 100 mA version.

Therefore:

5SV4342-0RC → 25 A, 30 mA

5SV4442-0RC → 25 A, 100 mA

The key difference is the residual-current operating threshold.

Difference from 300 mA Version

The 5SV4642-0RC is the corresponding 25 A, 4-pole, Type AC, 300 mA version.

Therefore:

5SV4342-0RC → 25 A, 30 mA

5SV4442-0RC → 25 A, 100 mA

5SV4642-0RC → 25 A, 300 mA

The correct sensitivity should be selected according to the complete electrical protection scheme.

Difference from 2-Pole Version

The 5SV4312-0RC and 5SV4412-0RC are 2-pole / 1+N variants for suitable single-phase applications, while the 5SV4342-0RC is a 4-pole / 3+N device for suitable three-phase-plus-neutral systems.

Therefore:

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

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

5SV4412-0RC → 25 A, 2-pole / 1+N, 100 mA
