Product Description

Siemens 5SV4444-0RC RCCB – 40A, 4-Pole, 100mA, Type AC, 415V

The Siemens 5SV4444-0RC 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 40 A rated current and 100 mA rated residual operating current.

The device is suitable for compatible 415 V class three-phase AC distribution systems, including industrial, commercial and building electrical panels where 100 mA residual-current protection is required.

Siemens 5SV4444-0RC Residual Current Circuit Breaker

The 5SV4444-0RC 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 / 3+N configuration is designed for three-phase systems with neutral, making it suitable for distribution boards, feeder circuits and electrical panels.

40 A Rated Current

The RCCB has a rated current of 40 A.

This makes it suitable for compatible three-phase distribution circuits and feeders where a 40 A RCCB is required.

The complete installation should be designed so that the RCCB operates within its rated electrical and environmental conditions.

100 mA Residual Current Sensitivity

The 5SV4444-0RC has a rated residual operating current of 100 mA.

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

The 100 mA sensitivity should be selected according to the protection design and applicable electrical installation requirements.

Type AC Residual Current Protection

The device is a Type AC RCCB, intended for compatible sinusoidal alternating residual currents.

The RCCB type should always be selected according to the possible residual-current waveform in the actual installation.

4-Pole / 3+N Configuration

The 5SV4444-0RC provides 4 poles, making it suitable for three-phase plus neutral circuits.

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

Typical applications include:

• Three-phase distribution boards

• PCC panels

• MCC panels

• Industrial feeder circuits

• Commercial distribution panels

• Factory electrical systems

• Equipment supply circuits

415 V AC Three-Phase Application

The supplied India product description identifies the device for 415 V AC applications.

It is intended for suitable three-phase low-voltage distribution systems. The actual system voltage and wiring arrangement should be verified against the installation design and applicable Siemens documentation.

Instantaneous Operation

The 5SV4444-0RC is part of the Siemens 5SV4 Type AC RCCB range designed for instantaneous residual-current protection.

Instantaneous operation means there is no intentional short-time delay before the device responds 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 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

• Electrical installation requirements

The RCCB should not be considered a replacement for an overcurrent protective device unless the overall protection arrangement specifically provides that function.

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 format is suitable for:

• Modular distribution boards

• Electrical control panels

• PCC panels

• Sub-distribution boards

• Commercial switchboards

• Industrial protection assemblies

Modular Distribution Installation

The 5SV4 RCCB format supports integration into conventional modular electrical distribution assemblies.

The device can be installed alongside compatible MCBs, busbars and other protection accessories according to the panel design.

Residual Current Protection

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

The RCCB monitors the relevant current balance and disconnects the circuit when the residual current reaches 100 mA.

This provides an additional level of protection within the overall electrical protection system.

Three-Phase Distribution Applications

The 5SV4444-0RC 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:

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

This combination can be useful for selected three-phase distribution and feeder applications.

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 functional.

Installation Considerations

Before selecting the 5SV4444-0RC, verify:

• Rated current: 40 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

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

Difference from 40 A, 300 mA Version

The 5SV4644-0RC is the corresponding 40 A, 4-pole, Type AC RCCB with a 300 mA residual-current threshold.

Therefore:

5SV4444-0RC → 40 A, 100 mA

5SV4644-0RC → 40 A, 300 mA

The primary difference is the residual-current sensitivity.

Difference from 30 mA Version

Siemens also offers Type AC RCCBs with lower residual-current sensitivities such as 30 mA.

The 5SV4444-0RC is specifically the 100 mA version, so the article number and residual-current threshold should be verified carefully when selecting a replacement.

Difference from 63 A Version

The 5SV4446-0RC is rated at 63 A, while 5SV4444-0RC is rated at 40 A.

Both belong to the 4-pole Type AC family with a 100 mA residual-current threshold.

Therefore:

5SV4444-0RC → 40 A

5SV4446-0RC → 63 A

Difference from 25 A Version

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

The 5SV4444-0RC is selected where a 40 A rated current is required.
