Type A residual sensitivity detects pulsating DC fault currents (rectified AC waveforms) in addition to sinusoidal AC, which is the typical requirement for single-phase electronics loads downstream of a rectifier. At 63 A and 4-pole, this unit covers three-phase + neutral final subcircuits up to that current. The 7-module width fits standard 18 mm per module DIN-rail enclosures; plan for the panel space before the BOM freeze.","metaTitle":"Siemens 5SU1344-7RC63 RCBO 63 A 4-pole C curve Type A 30mA","metaDescription":"Siemens 5SU1344-7RC63 RCBO, 63 A, 4-pole, C characteristic, Type A, 30 mA.
