5SV3642-4KK14 SIEMENS

The 5SV3642-4KK14 is a 4-pole residual current operated circuit breaker (RCCB) designed and manufactured by Siemens. This RCCB provides enhanced protection against electrical hazards by quickly disconnecting the circuit upon detecting a residual current, also known as earth leakage current. It is a Type B+ RCCB, making it suitable for detecting AC and pulsating DC residual currents, as well as residual currents with high frequency components. The device has a rated current (In) of 25 A and a residual current sensitivity (IΔn) of 300 mA. Its short-time delayed tripping characteristic ensures selectivity in cascaded RCCB systems, preventing nuisance tripping. The rated voltage (Un) is 400 V AC, making it compatible with standard three-phase power systems. This RCCB is ideal for applications where sensitive electronic equipment is used, as it minimizes the risk of unwanted shutdowns due to transient leakage currents. It enhances safety in electrical installations by providing reliable protection against electric shock and fire hazards. Siemens 5SV3642-4KK14 is a reliable and robust solution for residual current protection.
