Siemens 5SV3342-6RC Residual Current Circuit Breaker

The 5SV3342-6RC belongs to the Siemens SENTRON 5SV3 RCCB family. Its primary function is to monitor residual current and disconnect the protected circuit when the residual current reaches the specified operating threshold.

The 4-pole / 3+N configuration is designed for three-phase systems with neutral, making it suitable for compatible industrial, commercial and building electrical installations.

Siemens lists the corresponding 5SV3342-6 as an active product with a description of 4-pole, Type A, 25 A, 30 mA, 400 V AC.

25 A Rated Current

The RCCB 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 protected circuit should always be designed so that the RCCB operates within its specified electrical ratings and installation conditions.

30 mA Residual Current Sensitivity

The 5SV3342-6RC has a rated residual operating current of 30 mA. Siemens' current data sheet confirms 30 mA as the rated 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 complete electrical protection design and applicable installation requirements.

Type A Residual Current Protection

The device is a Type A RCCB.

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 RCCBs suitable for many modern installations containing electronic and rectifier-based loads.

Potential applications can include:

• Electronic power supplies

• Rectifier circuits

• Automation equipment

• Variable-speed equipment

• Industrial electronic machinery

• Modern commercial equipment

The appropriate RCCB type should always be selected according to the residual-current characteristics of the connected equipment.

4-Pole / 3+N Configuration

The 5SV3342-6RC has 4 poles, making it 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

• PCC panels

• MCC panels

• Industrial feeders

• Commercial electrical panels

• Sub-distribution boards

• Machine supply circuits

• Factory electrical systems

415 V India Application

The supplied India designation identifies the RCCB for 415 V AC applications.

Siemens' current technical data for the corresponding 5SV3342-6 specifies 400 V AC rated operating voltage.

For the SB Smart product listing, the 415 V India-market designation can be retained while actual installation selection should be checked against the Siemens technical rating and the electrical system design.

Instantaneous Operation

The 5SV3342-6RC is an instantaneous RCCB. Siemens specifies that the switching function is not short-time delayed.

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

10 kA Short-Circuit Current Rating

The corresponding Siemens 5SV3342-6 is specified with a 10 kA short-circuit current rating. The data sheet also specifies a maximum permissible 80 A series fuse for short-circuit coordination.

The RCCB should nevertheless be coordinated with suitable upstream overcurrent protection and the prospective short-circuit conditions of the installation.

An RCCB primarily provides residual-current protection and should not be treated as a substitute for an MCB or MCCB for overload and short-circuit protection unless the complete protection arrangement specifically provides those functions.

4-Module Design

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

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

The Siemens 2025 product catalogue identifies the Type A 3P+N range in a 4-module arrangement, including the 25 A article 5SV3342-6.

DIN Modular Installation

The corresponding 5SV3342-6 is classified as a size 1 installation device according to DIN 43880 and has 60 mm grid spacing.

This supports installation in conventional modular distribution boards and electrical panels.

The RCCB can be combined with compatible MCBs, busbars and supplementary protection accessories according to the panel design.

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 electrical enclosure or distribution assembly.

Residual Current Protection

Residual current occurs when part of the electrical current flows outside the intended circuit path, such as through an unintended leakage path to earth.

The RCCB monitors the 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 overall electrical safety system.

Applications with Electronic Loads

The Type A characteristic makes the 5SV3342-6RC suitable for installations where residual currents may contain pulsating DC components.

Potential applications include:

• Industrial automation equipment

• Electronic control panels

• Rectifier-based machinery

• Variable-speed equipment

• Commercial electronic equipment

• Modern machine installations

• Power-electronic loads

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

Three-Phase Distribution Applications

The 5SV3342-6RC 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 A + 4-pole / 3+N

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

Panel builders can use it where the protection design requires a Type A RCCB with a 25 A rated current and 30 mA residual-current threshold.

Protection Coordination

The RCCB should be coordinated with appropriate upstream overcurrent protection where required.

A typical arrangement can include:

Incoming Supply → MCB/MCCB → RCCB → Protected Load

The exact arrangement depends on the electrical system, upstream protective device and applicable installation requirements.

The RCCB's residual-current function should be considered separately from overload and short-circuit protection.

Maintenance and Testing

RCCBs should be included in the electrical installation's regular 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 protective mechanism remains operational.

Installation Considerations

Before selecting the 5SV3342-6RC, verify:

• Rated current: 25 A

• Residual-current sensitivity: 30 mA

• RCCB type: Type A

• Pole configuration: 4-pole / 3+N

• System voltage compatibility

• Upstream overcurrent protection

• Available panel space: 4 module width

• Conductor size and termination

• Connected equipment leakage-current characteristics

• Applicable national electrical regulations

The RCCB type should be selected according to the actual load and residual-current waveform.

Difference from Type AC 25 A, 30 mA Version

Therefore:

5SV3342-6RC → Type A, 25 A, 30 mA

5SV4342-0RC → Type AC, 25 A, 30 mA

The main difference is the residual-current type.

Difference from Type A 40 A Version

The 5SV3344-6RC is the corresponding 40 A, 4-pole, Type A, 30 mA version.

Therefore:

5SV3342-6RC → 25 A

5SV3344-6RC → 40 A

Both are Type A, 4-pole RCCBs with 30 mA residual-current sensitivity. Siemens' 2025 catalogue lists both articles together in this range.

Difference from Type A 63 A Version

The 5SV3346-6RC is the corresponding 63 A, 4-pole, Type A, 30 mA version.

Therefore:

5SV3342-6RC → 25 A

5SV3344-6RC → 40 A

5SV3346-6RC → 63 A

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

Difference from Type A 80 A Version

The 5SV3347-6 is the corresponding 80 A, 4-pole, Type A, 30 mA device in the Siemens product range.

Therefore:

5SV3342-6RC → 25 A

5SV3344-6RC → 40 A

5SV3346-6RC → 63 A

5SV3347-6 → 80 A

Difference from Type A 100 mA Version

The 5SV3442-6 is a 25 A, 4-pole, Type A, 100 mA RCCB in the Siemens 5SV3 range. Siemens' 2025 catalogue lists this article separately from the 30 mA 5SV3342-6.

Therefore:

5SV3342-6RC → 25 A, 30 mA

5SV3442-6 → 25 A, 100 mA

The main difference is the residual-current operating threshold.

Difference from Type A 300 mA Version

The 5SV3642-6RC belongs to the corresponding Type A range with a 300 mA residual-current threshold.

Therefore:

5SV3342-6RC → 25 A, 30 mA
