It accepts circuit breakers in sizes S00 and S0, making it a common interface part in motor control centers and distribution panels where the feeder and contactor need to be mechanically integrated on a DIN rail. The base measures 63.1 mm deep, 44.8 mm wide, and 159.8 mm high. The 0 mm backward clearance means the rear face sits flush against the mounting surface — no extra space needed behind the rail for wiring or airflow. This part is a mechanical and wiring interface — it has no coil, no auxiliary contacts, and no electronic logic. Its job is to hold the circuit breaker and route the power and control wiring to the contactor that mounts on top. For a 3RA2 load feeder build, the base is the first component you snap onto the rail; the breaker and contactor then clip onto it.","metaTitle":"Siemens 3RV2927-7AA00 SIRIUS Contactor Base, S00/S0, 63.1 mm","metaDescription":"Siemens SIRIUS 3RV2927-7AA00 contactor base for 3RA2 load feeders.
