It provides the wired interface for control and signal circuits on the draw-out chassis, allowing the main power contacts to be disconnected without disturbing the auxiliary wiring. Rated for a thermal current of 10 A and a minimum DC operating voltage of 250 V, this connector handles the typical control and signal loads found in 3VA breaker applications — think shunt trips, undervoltage releases, auxiliary contacts, and status indication circuits. ## Physical integration into the panel The connector measures 15 mm wide, 88 mm high, and 55 mm deep, with a stripped length of 15 mm (0.6 in) for termination. That 15 mm width matches a single modular unit on a DIN rail, so it slots into the same footprint as the draw-out unit's accessory bay without stealing extra space. The 55 mm depth is the projection from the mounting surface — verify clearance to the enclosure door or backplane.","metaTitle":"Siemens 3VA9987-0KD80 Auxiliary Circuit Connector, 10 A, 250","metaDescription":"Siemens SENTRON 3VA9987-0KD80 auxiliary circuit connector for 3VA draw-out units.
