Product Description
5SV5644-6
The Siemens 5SV5644-6 is a 4-pole Residual Current Circuit Breaker (RCCB) designed for reliable protection against electric shock and fire hazards caused by earth leakage currents. With a rated current of 40A and a residual operating current of 300mA, this RCCB is suitable for three-phase systems operating at 400 V AC. Its Type A sensitivity allows it to detect both sinusoidal AC and pulsating DC residual currents, making it highly effective in environments with modern electrical loads.

- Designed for circuits with electronic devices producing pulsating DC leakage currents
Summary:
The Siemens 5SV5644-6 RCCB is a 40A, 4-pole, Type A device with 300mA residual sensitivity, ensuring effective protection against earth leakage currents and fire risks. It is a robust safety solution for 400 V AC installations, making it ideal for both residential and commercial distribution systems.
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.
