Product Description
5SV5612-6
The Siemens 5SV5612-6 is a 2-pole Residual Current Operated Circuit Breaker (RCCB) designed to provide reliable protection against electric shock and fire hazards caused by earth leakage currents. With a 25A rated current and 300mA residual sensitivity, it is suitable for high-leakage or backup protection applications in residential, commercial, or light industrial installations. Operating at 230 V AC, this device features Type A sensitivity, capable of detecting both sinusoidal AC leakage currents and pulsating DC leakage currents.

Summary:
The Siemens 5SV5612-6 RCCB is a 25A, 2-pole device with 300mA residual sensitivity and Type A detection. It is optimized for circuits where higher leakage protection is required, providing reliable safety against electrical fires and shocks while ensuring compliance in modern single-phase installations.
Frequently Asked Questions
What is MCB protection?
✅ MCB (Miniature Circuit Breaker) protects against overloads and short circuits. Overload protection works via a bimetallic strip (thermal operation), while short-circuit protection uses a tripping coil (electromagnetic operation). This ensures electrical safety in homes, businesses, and industries.
What is the rule for installing an SPD?
✅ SPD (Surge Protection Device) connections should be as short as possible to minimize the voltage protection level (Up). The total length of connections to the network and earth should not exceed 50 cm to ensure effective surge protection.
How to Set Up a Surge Protector?
1.Turn off power at the circuit breaker.
2. Remove the old outlet.
3. Connect wires to the new surge-protected outlet per the manufacturer’s instructions.
4. Secure the outlet in the box and replace the cover plate.
5. Restore power and test the outlet.
What is the use of RCCB in Siemens?
✅ Siemens Residual Current Circuit Breakers (RCCBs) protect against electric shock by detecting leakage currents. If the leakage exceeds a set limit, the RCCB immediately disconnects the circuit, ensuring safety from direct or indirect contact with live components.
Where is an RCBO used?
✅ RCBOs (Residual Current Circuit Breakers with Overcurrent protection) are commonly used in various residential, commercial, and industrial applications. Typical use cases include power distribution boards, emergency lighting circuits, HVAC (Heating, Ventilation, and Air Conditioning) systems, socket outlets, and swimming pool equipment. RCBOs are ideal for protecting individual circuits where both earth fault and overcurrent protection are required.
Where to Install RCCB?
✅ RCCBs should be installed in the distribution board (DB box) or circuit breaker panel to protect against current leakages caused by faulty wiring, ageing insulation, or defective appliances.
