It provides two auxiliary switches for signaling the ON-to-OFF position of the main breaker. Rated for a thermal current of 5 A, the contacts carry AC-12 resistive loads at 5 A across 12 V to 240 V, AC-15 inductive loads at 2 A across the same voltage range, and DC-13 solenoid loads at 0.2 A from 12 V up to 250 V. The minimum DC operating voltage is 250 V, meaning the DC ratings apply only at or above that level.","metaTitle":"Siemens SENTRON 3VA9877-0GX42 Auxiliary Switch Module, 5 A","metaDescription":"Siemens SENTRON 3VA9877-0GX42 auxiliary switch module for 3VA57/58/59/67/68/69 rotary operators.
