Rated 5 A thermal current (Ith), it handles AC-12 loads up to 5 A at 240 V and AC-15 pilot-duty loads up to 2 A at 240 V — sufficient for most contactor coils and panel indicators in a 480 V MCC lineup. On DC control circuits, the DC-13 rating is 0.2 A at 24 V and 0.2 A at 250 V, so it handles solenoid valves and small DC relays but not high-inrush DC loads like large contactor holding coils without a suppression network. ## Environmental and isolation specs that matter for fit","metaTitle":"Siemens SENTRON 3VA9877-0GX41 Auxiliary Switch, 5 A, -40 to","metaDescription":"Siemens SENTRON 3VA9877-0GX41 auxiliary switch module for 3VA57/58/59 and 3VA67/68/69 breakers.
