5SV3347-4 SIEMENS

The 5SV3347-4 is a four-pole residual current operated circuit breaker (RCCB) meticulously engineered by Siemens to provide advanced protection against electrical faults. This RCCB is designed to detect residual currents, which indicate insulation failures or earth faults, and promptly interrupt the circuit to prevent electrical shocks and fire hazards. Featuring a Type B characteristic, it is suitable for circuits with sensitive electronic equipment, offering enhanced immunity to nuisance tripping caused by transient currents. The 5SV3347-4 has a rated current (In) of 80A, making it suitable for high-current applications in industrial and commercial settings. Its sensitivity is set at 30mA, ensuring rapid response to even small leakage currents, thereby maximizing safety. The RCCB is designed for a rated voltage (Un AC) of 400V, aligning with standard European power systems. The short-time delayed tripping characteristic allows for discrimination in selective protection schemes, preventing unwanted tripping during brief overcurrent events. This feature ensures continuity of power supply to other critical circuits. Siemens' 5SV3347-4 RCCB combines reliability, precision, and robustness, making it an ideal choice for comprehensive electrical safety in demanding environments. It adheres to stringent quality standards, guaranteeing long-term performance and peace of mind.
