Product Description

Siemens 5SV4446-0RC RCCB – 63A, 4-Pole, 100mA, Type AC, 415V

The Siemens 5SV4446-0RC is a SENTRON 5SV4 residual current operated circuit breaker (RCCB) designed for protection against residual AC currents in three-phase electrical installations with neutral. It is a 4-pole / 3+N Type AC RCCB with a 63 A rated current and 100 mA rated residual operating current. The device is intended for suitable 230/400 V AC distribution systems and is suitable for modular electrical panels and distribution boards.

Siemens 5SV4446-0RC Residual Current Circuit Breaker

The 5SV4446-0RC belongs to the Siemens SENTRON 5SV4 RCCB family. Its function is to detect residual current in the protected circuit and disconnect the circuit when the residual current reaches its specified operating threshold.

The 4-pole configuration is suitable for three-phase plus neutral circuits, making the device appropriate for industrial, commercial and building electrical distribution systems.

63 A Rated Current

The RCCB has a rated current of 63 A.

This makes the device suitable for compatible distribution feeders and electrical circuits designed for a 63 A residual-current protection device.

The complete protection arrangement should ensure that the device is operated within its rated current and installation conditions.

100 mA Residual Current Sensitivity

The 5SV4446-0RC 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.

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

Type AC Residual Current Protection

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

The correct RCCB type should always be selected according to the residual-current waveform that can occur in the installation.

4-Pole / 3+N Configuration

The 5SV4446-0RC uses a 4-pole configuration, suitable for three-phase plus neutral electrical systems.

This arrangement allows the phases and neutral to be included in the residual-current protection scheme.

Typical applications include:

• Three-phase distribution boards

• Industrial feeder circuits

• Commercial electrical panels

• PCC panels

• Sub-distribution boards

• Machine supply circuits

• Factory electrical systems

415 V AC / 240 V AC Three-Phase Systems

The India-facing product description identifies the device as 415 V AC. For compatible three-phase low-voltage systems, the device is used in the typical 240/415 V AC phase-neutral/phase-phase arrangement.

The actual system voltage and wiring must be verified against the applicable Siemens documentation and the electrical installation design.

Instantaneous RCCB

The 5SV4446-0RC belongs to the Siemens 5SV4 Type AC instantaneous RCCB range.

An instantaneous RCCB operates without an intentionally introduced short-time delay when the residual-current trip threshold is reached.

This makes it suitable where instantaneous residual-current protection is specified by the protection design.

10 kA Short-Circuit Rating

The Siemens 5SV4 range provides short-circuit coordination characteristics for suitable installations.

The RCCB should be installed with appropriate upstream overcurrent protection and coordinated with the prospective short-circuit current of the electrical system.

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

Modular 4-Module Design

The India product description specifies 4MW, meaning a 4-module-width modular installation format.

The 4MW designation refers to physical module width and does not indicate a 4 MW power rating.

The modular format is suitable for:

• Distribution boards

• Electrical control panels

• Commercial panels

• Industrial protection assemblies

• Sub-distribution systems

60 mm Grid Arrangement

The 5SV4 RCCB design is intended for standard modular electrical distribution installations with conventional grid spacing.

This supports integration into distribution-board assemblies alongside compatible MCBs, busbars and accessories.

Residual Current Protection

Residual current occurs when some electrical current leaves the intended circuit path, for example through an unintended earth-leakage path.

The RCCB monitors the circuit and trips when the residual current reaches the 100 mA operating threshold.

This provides an additional layer of electrical protection within the overall installation protection scheme.

Three-Phase Distribution Applications

The 5SV4446-0RC is suitable for compatible three-phase plus neutral applications such as:

• Main distribution boards

• Sub-distribution boards

• Industrial feeders

• Commercial distribution panels

• Factory electrical systems

• Building electrical installations

• Equipment feeders

• Electrical control panels

Industrial Panel Applications

Panel builders can use the device where the protection design requires:

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

This makes the RCCB suitable for three-phase circuits where a 100 mA residual-current threshold is specified.

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

Regular testing can help confirm that the protective mechanism remains operational.

Installation Considerations

Before selecting the 5SV4446-0RC, verify:

• Rated current: 63 A

• Residual-current sensitivity: 100 mA

• RCCB type: Type AC

• Pole configuration: 4-pole / 3+N

• System voltage: compatible 3-phase AC supply

• Upstream overcurrent protection

• Panel space: 4 module width

• Conductor size and termination

• Applicable national electrical regulations

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

Difference from 300 mA Version

The 5SV4646-0RC is the corresponding 63 A, 4-pole, Type AC RCCB with a 300 mA residual-current sensitivity.

Therefore:

5SV4446-0RC → 63 A, 100 mA

5SV4646-0RC → 63 A, 300 mA

The main difference is the residual-current operating threshold.

Difference from 30 mA Version

The corresponding 30 mA version belongs to the same 63 A, 4-pole Type AC family but provides a lower residual-current operating threshold.

Therefore, the selection should be based on whether the application requires:

• 30 mA

• 100 mA

• 300 mA

The correct sensitivity depends on the intended protection function and applicable standards.

Difference from 80 A Version

The 5SV4447-0RC is the higher-current 80 A version, whereas the 5SV4446-0RC is rated at 63 A.

Both are used as 4-pole Type AC RCCBs with the corresponding residual-current sensitivity.

Difference from 4-Pole 300 mA RCCB

The 5SV4646-0RC has:

63 A + 4-pole + Type AC + 300 mA

The 5SV4446-0RC has:

63 A + 4-pole + Type AC + 100 mA

This distinction is important when selecting a replacement device.
