The Siemens 5SU1624-1RC63 is a 2-pole RCBO (residual current circuit breaker with overcurrent protection) rated 63 A, C characteristic, Type AC, 300 mA sensitivity, in a 4-module DIN-rail housing. The Type AC residual-current detection handles sinusoidal AC faults only; if the downstream load includes VFDs, switched-mode supplies, or rectifiers that generate pulsed DC fault currents, specify a Type A or Type F instead.
