5SV3321-4 SIEMENS

The 5SV3321-4 is a 2-pole residual current operated circuit breaker (RCCB) from Siemens, designed to provide enhanced protection against electrical hazards. This device is engineered to detect residual currents, which indicate a leakage of current to earth, and immediately interrupt the circuit to prevent electric shock and fire. Featuring a Type B tripping characteristic, the RCCB is suitable for circuits with sensitive electronic equipment where nuisance tripping needs to be avoided. The short-time delayed tripping mechanism ensures selectivity in cascaded RCCB systems, preventing the entire installation from shutting down in the event of a fault. With a rated current (In) of 16A and a tripping current (Idn) of 30mA, this RCCB is ideal for residential and commercial applications. It operates at a rated voltage (Un) of 230V AC. The 5SV3321-4 RCCB offers reliable protection and contributes to a safer electrical environment. Its robust design and compliance with international standards ensure long-lasting performance and peace of mind. This device is an essential component for modern electrical installations, safeguarding people and property from the dangers of electrical faults.
