5SV3642-6KK01 SIEMENS

The 5SV3642-6KK01 is a four-pole residual current operated circuit breaker (RCCB) meticulously engineered by Siemens to provide advanced protection against electrical faults. This RCCB is specifically designed to detect residual currents, which indicate insulation failures or earth faults, thereby preventing electrical shocks and fire hazards. It is a Type A RCCB, making it sensitive to both alternating and pulsating DC residual currents, ensuring comprehensive protection in various applications. The device has a rated current (In) of 25A, indicating its capacity to handle continuous loads up to 25 amperes. With a tripping current (IΔn) of 300mA, it offers a balance between sensitivity and immunity to nuisance tripping caused by transient leakage currents. The 5SV3642-6KK01 is designed for a rated voltage (Un) of 400V AC, making it suitable for three-phase power systems commonly found in industrial and commercial settings. Its short-time delayed tripping characteristic allows for discrimination in cascaded protection systems, preventing unnecessary shutdowns. This RCCB is an essential component for ensuring electrical safety and equipment protection in modern electrical installations.
