Product Description

Siemens 5SV4344-0RC RCCB – 40A, 4-Pole, 30mA, Type AC, 415V

The Siemens 5SV4344-0RC 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 40 A rated current and 30 mA rated residual operating current. Siemens' technical data identifies the corresponding 5SV4344-0 as an instantaneous 4-pole Type AC RCCB, rated 40 A, 30 mA and 400 V AC.

The India-facing product designation specifies 415 V, 4MW, making it suitable for compatible three-phase distribution boards, electrical panels and feeder applications.

Siemens 5SV4344-0RC Residual Current Circuit Breaker

The 5SV4344-0RC belongs to the Siemens SENTRON 5SV4 RCCB family. Its primary purpose is to detect residual current in the protected circuit and disconnect the circuit when the residual current reaches the specified operating threshold.

Its 4-pole / 3+N configuration is intended for three-phase systems with neutral, making it suitable for industrial, commercial and building electrical distribution applications.

40 A Rated Current

The RCCB has a rated current of 40 A.

This makes it suitable for compatible three-phase circuits and feeders where a 40 A residual-current protection device is required.

The complete electrical installation should ensure that the device operates within its specified current, voltage and environmental conditions.

30 mA Residual Current Sensitivity

The 5SV4344-0RC has a rated residual operating current of 30 mA. Siemens specifies the tripping fault current as 30 mA for the corresponding 5SV4344-0 article.

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

The appropriate residual-current sensitivity should always be selected according to the actual protection design and applicable electrical regulations.

Type AC Residual Current Protection

The device is a Type AC RCCB.

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

4-Pole / 3+N Configuration

The 5SV4344-0RC 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 scheme.

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 AC / 400 V AC Three-Phase Application

The supplied India product description identifies this model as 415 V AC. Siemens' technical data for the corresponding 5SV4344-0 specifies 400 V AC rated supply voltage.

For the SB Smart product listing, the 415 V India designation can be retained, while actual installation selection should be based on the Siemens-rated system voltage and the electrical installation requirements.

Instantaneous Operation

The 5SV4344-0RC is an instantaneous RCCB. Siemens specifies that the switching function is not short-time delayed.

This means the RCCB operates without an intentional short-time delay when the specified residual-current threshold is reached.

10 kA Short-Circuit Current Rating

Siemens specifies a 10 kA short-circuit current rating for the corresponding 5SV4344-0 article.

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 catalogue identifies the Type AC 3P+N 5SV4 family as a 4 MW modular arrangement.

This makes the device suitable for:

• Modular distribution boards

• Electrical control panels

• PCC panels

• Sub-distribution boards

• Commercial switchboards

• Industrial protection assemblies

DIN Modular Installation

The 5SV4344-0RC is designed for modular electrical installation.

Siemens identifies the corresponding device as size 1 according to DIN 43880, supporting conventional modular distribution-board arrangements.

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

60 mm Grid Spacing

Siemens specifies 60 mm grid spacing for the corresponding 5SV4344-0 device.

This supports integration into standard modular electrical distribution assemblies.

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 protected circuit when the residual current reaches the 30 mA operating threshold.

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

Three-Phase Distribution Applications

The 5SV4344-0RC 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 + 30 mA + Type AC + 4-pole / 3+N

This combination can be used for selected three-phase residual-current protection applications.

The use of a 30 mA device should be evaluated against the connected load, leakage-current characteristics and applicable installation requirements.

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 5SV4344-0RC, verify:

• Rated current: 40 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 states that these devices are not permitted in all countries and that national installation regulations must be observed.

Difference from 25 A Version

The 5SV4342-0 is the corresponding 25 A, 4-pole, Type AC, 30 mA variant, while the 5SV4344-0 is rated at 40 A. Siemens' 2025 catalogue lists both within the same Type AC 3P+N family.

Therefore:

5SV4342-0RC → 25 A, 30 mA

5SV4344-0RC → 40 A, 30 mA

The principal 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:

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:

5SV4344-0RC → 40 A

5SV4346-0RC → 63 A

5SV4347-0RC → 80 A

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

Difference from 100 mA Version

The 5SV4444-0RC is the corresponding 40 A, 4-pole, Type AC, 100 mA version.

Therefore:

5SV4344-0RC → 40 A, 30 mA

5SV4444-0RC → 40 A, 100 mA

The key difference is the residual-current operating threshold.

Difference from 300 mA Version

The 5SV4644-0RC is the corresponding 40 A, 4-pole, Type AC, 300 mA version.

Therefore:

5SV4344-0RC → 40 A, 30 mA

5SV4444-0RC → 40 A, 100 mA

5SV4644-0RC → 40 A, 300 mA

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

Difference from 2-Pole Version

The 5SV4314-0RC and 5SV4414-0RC are 2-pole / 1+N versions intended for single-phase applications, whereas the 5SV4344-0RC is a 4-pole / 3+N device for three-phase-plus-neutral systems.

Therefore:

5SV4344-0RC → 40 A, 4-pole / 3+N, 30 mA

5SV4314/4414 family → 40 A, 2-pole / 1+N variants
