It's listed as Type A (sensitive to pulsating DC fault currents up to 6 mA), with a rated residual current IΔN of 30 mA and a short-circuit breaking capacity of 6 kA. The thermal-magnetic trip curve is C, rated 32 A. That means it protects a final subcircuit against both earth faults and overload/short-circuit, all in one DIN-rail unit. The C-curve (32 A) means the magnetic trip operates at 5 to 10 times rated current, so it's a good fit for circuits with moderate inrush — think small motors, pumps, or groups of fluorescent lighting — without nuisance tripping on start-up.","metaTitle":"Siemens 5SU1356-7KV32 FI/LS Protector, Type A, 30mA, 6kA, 1+","metaDescription":"Siemens 5SU1356-7KV32 FI/LS-protector Type A (PSE/SSF), 30mA, 6kA, 1+N-pole C 32A.
