Product Description
5SV3642-4
The Siemens 5SV3642-4 is a 4-pole residual current operated circuit breaker (RCCB) engineered for demanding electrical environments that require comprehensive protection against various types of residual currents. Classified as a Type B RCCB, it can detect AC, pulsating DC, and smooth DC fault currents, making it suitable for use with equipment such as inverters, EV charging stations, medical devices, and frequency converters.
With a rated current of 25 A and residual current sensitivity of 300 mA, the device provides reliable protection against fire hazards and electrical faults in both residential and industrial systems operating at 400 V AC.
The breaker features a short-time delay to prevent unwanted tripping caused by transient leakage currents during normal operation. Additionally, it belongs to the SIGRES series, specially designed to withstand harsh ambient conditions such as humidity, dust, or chemical exposure, and supports extended test intervals for improved maintenance efficiency.

Frequently Asked Questions
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.
