That 15 mm width matches a single modular unit on a DIN rail, so it slots into the draw-out unit's accessory bay without stealing space from adjacent breaker positions. The stripped length is 15 mm (0.6 in) — standard for the spring-cage terminals on SENTRON accessories. This is the auxiliary circuit connector that plugs into the draw-out unit's secondary disconnect block. It carries control wiring — not main power — from the fixed part of the switchgear to the removable breaker cradle. The 10 A thermal current is ample for signaling, status contacts, and shunt-trip feeds typical in 3VA-based distribution panels.","metaTitle":"Siemens SENTRON 3VA9977-0KD80 Auxiliary Circuit Connector, 1","metaDescription":"Siemens SENTRON 3VA9977-0KD80 auxiliary circuit connector for 3VA draw-out units.
