The thermal-magnetic release follows a B-curve characteristic, tripping at 3–5× rated current, and the unit is rated for 32 A continuous load. The pigtail connection on the neutral side simplifies wiring in pre-assembled consumer units. The 70 mm depth (D=70 mm) is standard for Siemens 5SU series devices, so it fits existing enclosures without extra gland-plate clearance. Type AC detection means it is intended for circuits with sinusoidal residual currents — typical for general-purpose socket outlets, lighting, and resistive loads. It is not rated for pulsating DC or smooth DC fault currents (those call for Type A or Type F devices).","metaTitle":"Siemens 5SU1356-0DA32 FI/LS Protector, Type AC, 30mA, 6kA, B","metaDescription":"Siemens 5SU1356-0DA32 FI/LS protector, Type AC, 30mA sensitivity, 6kA breaking capacity, 1+N pole, B-curve 32A, pigtail connection.
