Siemens 5SV3312-6RC Residual Current Circuit Breaker

The 5SV3312-6RC belongs to the Siemens SENTRON 5SV3 RCCB family. Its primary function is to detect residual current in the protected circuit and disconnect the circuit when the residual-current level reaches the specified operating threshold.

The 2-pole / 1+N configuration is intended for suitable single-phase systems where phase and neutral are incorporated into the residual-current protection arrangement.

Siemens' product catalogue identifies the corresponding 5SV3312-6 as a 2-pole, Type A, 25 A, 30 mA, 230 V AC RCCB and lists it as an active product.

25 A Rated Current

The RCCB has a rated current of 25 A.

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

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

30 mA Residual Current Sensitivity

The 5SV3312-6RC has a rated residual operating current of 30 mA. Siemens technical data confirms the 30 mA tripping residual current and 25 A rated 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 devices useful for installations containing modern electronic and rectifier-based loads.

Potential applications include:

• Electronic power supplies

• Rectifier-based equipment

• Automation equipment

• Variable-speed equipment

• Industrial electronic machinery

• Modern commercial electrical equipment

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

2-Pole / 1+N Configuration

The 5SV3312-6RC has 2 poles and is intended for 1+N single-phase applications.

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

Typical applications include:

• Single-phase distribution boards

• Commercial electrical panels

• Building electrical installations

• Office electrical systems

• Equipment feeders

• Sub-distribution circuits

• Industrial auxiliary circuits

240 V India Application / 230 V Siemens Rating

The supplied India product designation identifies the device as 240 V, 2MW.

Siemens' official product data for 5SV3312-6 specifies 230 V AC rated operating voltage.

For the SB Smart product page, the 240 V India-market designation can be retained, while the exact Siemens technical rating should be considered when selecting the device for an installation.

Instantaneous Operation

The 5SV3312-6RC is an instantaneous RCCB. Siemens' technical data specifies that the switching function is not short-time delayed.

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

10 kA Short-Circuit Rating

The corresponding Siemens 5SV3312-6 has a specified 10 kA short-circuit current rating. Siemens also specifies a maximum permissible 63 A series fuse for short-circuit protection 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.

Compact 2-Module Design

The India product description specifies 2MW, meaning 2 module width.

The 2MW designation refers to the physical modular width and does not indicate a 2 MW power rating. Siemens' product-selection data places the Type A 1P+N 25 A, 30 mA device within the 2-module format.

This compact format is suitable for:

• Modular distribution boards

• Consumer units

• Commercial electrical panels

• Sub-distribution boards

• Compact electrical enclosures

DIN Modular Installation

The 5SV3312-6RC is designed for modular electrical installation.

Siemens technical data identifies the corresponding device as size 1 according to DIN 43880, with a physical width of approximately 36 mm and a 60 mm grid spacing.

This allows convenient integration into suitable DIN-type distribution assemblies alongside compatible MCBs, busbars and other protection accessories.

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 through an unintended path, such as leakage to earth.

The RCCB monitors the relevant 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 complete electrical safety system.

Applications with Electronic Loads

The Type A characteristic makes the 5SV3312-6RC suitable for compatible installations where residual currents may include pulsating DC components.

Potential applications include:

• Industrial automation equipment

• Electronic control panels

• Rectifier-based machinery

• Variable-speed equipment

• Commercial electronic systems

• Modern machine installations

• Power-electronic loads

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

Single-Phase Distribution Applications

The 5SV3312-6RC can be considered for compatible single-phase applications such as:

• Residential distribution boards

• Commercial electrical panels

• Building electrical systems

• Office electrical circuits

• Equipment supply circuits

• Single-phase feeder protection

• Industrial auxiliary circuits

The final protection application should be determined according to the electrical design and applicable regulations.

Protection Coordination

An RCCB should be coordinated with suitable overcurrent protection where required.

A typical arrangement can be:

Incoming Supply → MCB/MCCB → RCCB → Protected Load

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

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

Maintenance and Testing

RCCBs should be included in an appropriate electrical 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 can help confirm that the protection mechanism remains operational.
