Siemens 5SU9356-2CN32 RCBO 1+N 6 kA D curve 32 A

The Siemens 5SU9356-2CN32 is a 1+N pole residual current circuit breaker with overcurrent protection (RCBO) rated at 32 A with a 6 kA breaking capacity. The D characteristic means it's designed to handle high inrush currents — think motor starts, welding equipment, or transformer energisation — without nuisance tripping. The Type AC residual sensing covers sinusoidal AC fault currents only, so it's suited for standard resistive and inductive loads without electronics or DC components.
