Siemens 5SV4442-0RC RCCB – 25A, 4-Pole, 100mA, Type AC, 415V

The Siemens 5SV4442-0RC is a SENTRON 5SV4 residual current operated circuit breaker (RCCB) designed for residual-current protection in suitable three-phase electrical installations with neutral. It is a 4-pole / 3+N Type AC RCCB with a 25 A rated current and 100 mA rated residual operating current. Siemens identifies the corresponding 5SV4442-0 article as a 4-pole, Type AC RCCB, In 25 A, 100 mA, Un AC 400 V, with instantaneous operation.

Siemens 5SV4442-0RC Residual Current Circuit Breaker

The 5SV4442-0RC belongs to the Siemens SENTRON 5SV4 RCCB family. Its purpose is to detect residual current in the protected circuit and disconnect the circuit when the residual current reaches the specified operating threshold.

The 4-pole configuration is intended for three-phase plus neutral (3+N) systems, making it suitable for industrial, commercial and building electrical distribution applications.

Siemens' 2025 product catalogue includes 5SV4442-0 in the Type AC, 3P+N, 4-module RCCB range.

25 A Rated Current

The RCCB has a rated current of 25 A.

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

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

100 mA Residual Current Sensitivity

The 5SV4442-0RC has a rated residual operating current of 100 mA.

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

A 100 mA RCCB should be selected where this residual-current sensitivity is appropriate for the overall protection scheme and applicable electrical requirements.

Type AC Residual Current Protection

The device is a Type AC RCCB.

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

4-Pole / 3+N Configuration

The 5SV4442-0RC 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 Three-Phase Application

The supplied India product designation specifies 415 V for this RCCB. Siemens' technical data for the corresponding 5SV4442-0 article specifies 230/400 V AC supply voltage, while Siemens' India market-facing naming uses the 415 V class designation.

For the product page, it is appropriate to retain the 415 V India designation while selecting the device according to the actual system voltage and applicable Siemens documentation.

Instantaneous Operation

The 5SV4442-0RC is designed for instantaneous residual-current operation.

Siemens specifies that the corresponding 5SV4442-0 RCCB does not have a short-time delayed switching function.

This means the device is intended to respond without an intentional short-time delay when the specified residual-current threshold is reached.

Short-Circuit Protection and Coordination

An RCCB primarily provides residual-current protection. It should be coordinated with suitable upstream overcurrent protection where required.

The overall protection arrangement should consider:

• Prospective short-circuit current

• Upstream MCB/MCCB protection

• Rated current

• Conductor size

• Electrical installation requirements

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

The corresponding 5SV4442-0 device is specified with 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 of the device and does not represent a 4 MW power rating.

This makes the RCCB suitable for modular installations such as:

• Distribution boards

• Electrical control panels

• PCC panels

• Sub-distribution boards

• Industrial protection assemblies

• Commercial switchboards

DIN Modular Installation

The 5SV4 RCCB is designed for installation in suitable modular electrical distribution assemblies.

The modular format allows the device to be installed alongside compatible MCBs, busbars and supplementary accessories according to the panel design.

Residual Current Protection

Residual current can occur when some current flows outside its intended electrical path, such as through an unintended earth-leakage path.

The RCCB monitors the current balance and disconnects the protected circuit when the residual current reaches the 100 mA operating threshold.

This provides an additional protection layer within the overall electrical safety system.

Three-Phase Distribution Applications

The 5SV4442-0RC 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 device is particularly relevant where the protection design requires:

25 A + 100 mA + Type AC + 4-pole / 3+N

This combination can be used for selected three-phase distribution and feeder applications where a 100 mA residual-current threshold is specified.

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 electrical-maintenance requirements to verify correct residual-current tripping.

Regular testing helps confirm that the protective mechanism remains operational.

Installation Considerations

Before selecting the 5SV4442-0RC, verify:

• Rated current: 25 A

• Residual-current sensitivity: 100 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 30 mA Version

The 5SV4342-0RC is the corresponding 25 A, 4-pole, Type AC RCCB with a 30 mA residual-current threshold, while the 5SV4442-0RC uses a 100 mA threshold. The Siemens 2025 catalogue lists both variants in the Type AC 3P+N family.

Therefore:

5SV4342-0RC → 25 A, 30 mA

5SV4442-0RC → 25 A, 100 mA

The appropriate sensitivity should be selected according to the intended protection function.

Difference from 300 mA Version

The 5SV4642-0RC is the corresponding 25 A, 4-pole, Type AC RCCB with a 300 mA residual-current threshold. Siemens India lists this model separately.

Therefore:

5SV4442-0RC → 25 A, 100 mA

5SV4642-0RC → 25 A, 300 mA

Difference from 40 A Version

The 5SV4444-0RC is the higher-current version in the same general Type AC, 4-pole, 100 mA family.

Therefore:

5SV4442-0RC → 25 A

5SV4444-0RC → 40 A

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

Difference from 63 A Version

The 5SV4446-0RC is the 63 A, 4-pole, Type AC, 100 mA version, while the 5SV4442-0RC is rated at 25 A.

This makes the article number important when selecting an exact replacement.
