5SV3644-6KK12 SIEMENS

The 5SV3644-6KK12 is a four-pole residual current operated circuit breaker (RCCB) from Siemens, designed to provide enhanced protection against electrical hazards. This type A RCCB is specifically engineered to detect AC and pulsating DC residual currents, ensuring a rapid response to potential fault conditions. With a rated current (In) of 40A and a residual current sensitivity of 300mA, it is suitable for applications where a higher level of fault current protection is required. The device is designed for a rated voltage (Un AC) of 400V, making it compatible with standard industrial and commercial power systems. The 5SV3644-6KK12 is part of the SIGRES series, indicating its suitability for harsh ambient conditions, offering increased resistance to environmental factors such as humidity, dust, and temperature variations. This robust construction ensures reliable performance and a prolonged lifespan in demanding environments. It promptly interrupts the circuit upon detection of a fault current, minimizing the risk of electric shock and preventing potential fire hazards. This RCCB contributes significantly to electrical safety in various applications. Its reliable performance and durable design make it a dependable choice for protecting both people and equipment.
