Type A sensitivity detects pulsating DC fault currents, covering electronics and single-phase rectifier loads that a plain AC type would miss. The 2-module (36 mm) width snaps onto DIN rail in a standard distribution board. Two poles switch both line and neutral; the outgoing terminals accept copper conductors up to 25 mm². Panel builders should account for the 300 mA residual-current threshold when coordinating downstream RCDs — this is a higher threshold than a 30 mA unit, intended for equipment protection rather than personal shock protection.","metaTitle":"Siemens 5SU1654-7RC40 RCBO 40 A 2-pole, C char, Type A 300 m","metaDescription":"Siemens 5SU1654-7RC40 RCBO, 40 A, 2-pole, 2-module, C characteristic, Type A 300 mA residual current.
