Product Description
5SV3342-4
The Siemens 5SV3342-4 is a high-performance 4-pole Residual Current Circuit Breaker (RCCB) engineered to ensure safety in three-phase power distribution systems. With Type B residual current sensitivity, it detects sinusoidal AC, pulsed DC, and smooth DC leakage currents, making it ideal for protecting modern loads such as frequency converters, EV chargers, and photovoltaic inverters. Rated at 25 A and designed with a short-time delayed tripping mechanism, this RCCB helps reduce nuisance tripping caused by transient currents. As part of the SIGRES series, it is built for harsh environmental conditions including humidity, dust, and chemical exposure.

Applications
- Suitable for use in industrial and commercial three-phase power systems
- Ideal for installations exposed to extreme conditions such as moisture, dust, or corrosive substances
- Perfect for protecting sensitive equipment such as EV charging stations, solar inverters, and UPS systems
- Provides fast and reliable disconnection in case of earth faults, while reducing false tripping during inrush currents
Summary:
The 5SV3342-4 RCCB by Siemens offers dependable protection for 25A three-phase circuits operating at 400V AC. Featuring Type B sensitivity, a short-time delayed tripping mechanism, and SIGRES environmental resilience, it ensures maximum safety and durability in critical and demanding applications. A trusted choice for ensuring electrical safety in modern installations.
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.
