It's a Type AC device, meaning it detects sinusoidal AC residual currents only, not pulsating DC or smooth DC. The 30 mA trip threshold is the standard for personal protection against electric shock in residential and commercial final circuits. Rated at 32 A with a B-curve magnetic trip, so it's sized for general-purpose socket outlets and lighting circuits where the inrush isn't severe — think resistive and light inductive loads, not motor starting. The 1+N-pole format switches the line conductor and disconnects the neutral, which is the usual arrangement for single-phase final circuits in TN and TT systems. 70 mm deep — check the enclosure depth before committing; some shallow consumer units are tight.","metaTitle":"Siemens 5SU1353-0KV32 FI/LS Protector, Type AC, 30mA, 4.5kA,","metaDescription":"Siemens 5SU1353-0KV32 FI/LS protector (RCBO), Type AC, 30mA, 4.5kA, 1+N-pole, B-curve 32A.
