The Siemens 5SU1153-0KV10 is a combined residual-current and miniature circuit breaker (RCBO) — an FI/LS protector — rated Type AC (WS), 10 mA trip sensitivity, 4.5 kA breaking capacity, 1+N-pole, B-curve 10 A. The 10 mA sensitivity (Type AC, sinusoidal AC residual only) is sized for wet-location or medical-grade circuits where a standard 30 mA RCD would not catch low-level leakage; the B-curve 10 A overcurrent side handles resistive and light inductive loads up to 2.3 kW at 230 V.

Frequently asked questions
What is 5SU1153-0KV10 used for?
It is a combined RCD/MCB (RCBO) for DIN-rail distribution boards, providing both earth-leakage protection (10 mA, Type AC) and overcurrent protection (B-curve, 10 A) in a single 1+N-pole module — typically used in wet areas, medical circuits, or any circuit requiring high-sensitivity residual-current protection.
