Type A sensitivity catches pulsating DC fault currents from single-phase rectifiers, which a plain AC type would miss. The 300 mA trip threshold is typical for socket-outlet circuits in commercial or light-industrial panels where earth-leakage alarms, not immediate disconnection, are the goal.","metaTitle":"Siemens 5SU1654-7RC20 RCBO 20 A 2-pole C-curve Type A 300mA","metaDescription":"Siemens 5SU1654-7RC20 RCBO, 20 A, 2-pole, 2-module, C characteristic, Type A 300mA.

Type A residual-current detection catches pulsating DC fault currents from single-phase rectifiers, and the 300 mA threshold suits socket-outlet circuits where earth-leakage alarms are preferred over immediate disconnection."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU1654-7RC20","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SU1654-7RC20 when reusing this data.
