The Siemens Residual current operated circuit breaker has 4-pole and type A. Used for short-time delayed. Operating current is 40 A and trippening residual current 300 mA. Supply voltage is 400 V. RCD is the residual current device for touch protection RCCBs, type A trip with both sinusoidal alternating currents (type AC) and pulsating DC residual currents. They are used mainly with single-phase consumers with electrical components in the supply unit, e.g. in residential and functional structures. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets for safe and efficient electrical infrastructure in buildings and industry.
