Product Description
5SV3647-8
The Siemens 5SV3647-8 is a 4-pole Residual Current Operated Circuit Breaker (RCCB) with selective tripping capability, ensuring enhanced coordination in multi-stage protection systems. Designed for 80A rated current and 400 V AC operation, this RCCB offers reliable protection against electric shock and fire hazards caused by earth leakage currents. With Type A sensitivity, it detects both sinusoidal AC and pulsating DC residual currents, making it suitable for modern installations that include electronic loads.

- Designed for circuits supplying critical or sensitive equipment where continuity of service and coordinated tripping are essential
Summary:
The Siemens 5SV3647-8 RCCB is a high-performance 80A, 4-pole protective device with 300mA residual sensitivity and selective tripping capability. By combining Type A residual current detection with selective operation, it ensures enhanced safety, reliability, and coordination in complex electrical distribution networks. This makes it a trusted solution for modern residential, commercial, and industrial applications.
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.
