Product Description
5SV3321-4
The Siemens 5SV3321-4 is a 2-pole Residual Current Circuit Breaker (RCCB) designed to provide advanced protection in electrical systems. Featuring a Type B sensitivity, this device detects smooth DC currents, pulsed DC currents, and AC leakage currents—making it suitable for modern applications such as EV charging stations, frequency converters, or photovoltaic systems. It has a short-time delayed tripping characteristic to reduce nuisance tripping and belongs to the SIGRES series, which is specially designed for harsh ambient conditions.

Applications
- Ideal for use in environments with increased air humidity, dust, or chemical exposure (SIGRES conditions)
- Suitable for modern loads with smooth DC components, such as EV chargers, drives, UPS systems, and solar inverters
- Ensures personal protection and fire prevention by quickly disconnecting faulty circuits
- Optimized for installations requiring reduced false tripping through short-time delay function
Summary:
The 5SV3321-4 RCCB from Siemens is a premium safety component designed for 16A-rated circuits requiring Type B residual current protection. Its short-time delay function enhances reliability by avoiding unnecessary shutdowns, and the SIGRES variant ensures durability even in extreme operating environments. This RCCB is a future-proof choice for demanding residential, commercial, and industrial electrical 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.
