It provides both earth-fault protection (Type AC, 30 mA trip threshold) and overcurrent/short-circuit protection (B-curve, 32 A rated current) in one unit, saving a DIN position compared to separate RCD and MCB. The B-curve (3–5× In) means it trips instantaneously on moderate overloads, typical for resistive and general-purpose loads. ## Panel integration and deployment Snap-on mounting to standard 35 mm DIN rail. The 70 mm depth (D=70mm) clears most enclosure back panels; verify clearance for the outgoing cable entry and the test-button access. The 1+N-pole format switches and protects the live conductor only; the neutral is switched but not protected — common for TN-S and TN-C-S systems where the neutral is bonded at the origin.","metaTitle":"Siemens 5SU1356-0KV32 RCBO, 30mA, 6kA, B 32A, 1+N","metaDescription":"Siemens 5SU1356-0KV32 FI/LS-protector Type AC, 30mA trip, 6kA breaking capacity, B-curve 32A, 1+N-pole.
