It integrates Type AC earth-leakage detection (30 mA trip threshold) with a 6 kA breaking-capacity MCB on the same 1+N-Pole DIN-rail footprint. The C 32 A thermal-magnetic characteristic means it handles inrush from motor or lighting loads up to 32 A while tripping instantaneously on short circuits. This single-module unit saves a DIN position compared to separate RCD + MCB. ## Deployment context The 70 mm depth (D=70MM) fits standard distribution boards and sub-distribution panels.","metaTitle":"Siemens 5SU1356-1KV32 FI/LS Protector, Type AC, 30mA, 6kA, 1","metaDescription":"Siemens 5SU1356-1KV32 FI/LS protector, Type AC, 30mA, 6kA, 1+N-Pole C 32A.
