It integrates Type AC earth-leakage detection at 30 mA with a B-curve overcurrent trip rated 16 A, all within a 70 mm wide housing. The 70 mm width (D=70MM) means this unit occupies 4 standard 17.5 mm DIN-rail modules. The 1+N-pole configuration switches the phase conductor and provides a switched neutral — the neutral pole is not protected against overcurrent but is disconnected when the device trips. Verify the neutral bar arrangement in the distribution board: this unit requires a dedicated neutral connection that passes through the residual-current summation transformer.","metaTitle":"Siemens 5SU1356-0KV16 FI/LS Protector, 30mA, 6kA, B 16A","metaDescription":"Siemens 5SU1356-0KV16 FI/LS protector, Type AC, 30mA, 6kA, 1+N-pole B 16A.
