It clips into the rotary operator accessory slot on those frames — no separate wiring channel needed, just snap it on and terminate the flying leads. Rated thermal current (Ith) is 5 A, which governs the continuous current the contacts can carry in any duty. Switching capacity varies by circuit type and voltage: 5 A in AC-12 (resistive loads) from 12 V up to 240 V; 2 A in AC-15 (solenoid/contactor coils) across the same voltage range; and 0.2 A in DC-13 (solenoid valves, contactor coils on DC) from 12 V up to 250 V. That DC-13 rating is the one to watch — if you're switching a 24 VDC pilot valve, the 0.2 A limit is the hard ceiling, not the 5 A thermal number. ## Environmental and insulation ratings That means it's suited for industrial control panels where dust, humidity, or condensation are present — not just clean conditioned rooms. The 3VA9877-0GX32 carries an active lifecycle status from Siemens. It's a current-production accessory for the SENTRON 3VA series, not a last-time-buy or NRND item.","metaTitle":"Siemens SENTRON 3VA9877-0GX32 Auxiliary Switch Module, 5 A","metaDescription":"Siemens SENTRON 3VA9877-0GX32 auxiliary switch module for 3VA57/58/59 & 3VA67/68/69 breakers.
