The Siemens 3RV1985-1DA0 is an extended terminal accessory for the front of a 3RV1 motor-protective circuit breaker. It comes as a pack of 6 units, designed to simplify wiring access in panels where the breaker is mounted deeper in the enclosure. The lifecycle stage is current, so this is a standard production part within the SIRUS range.
What it does on the panel
This extended terminal brings the connection point forward on the 3RV1 breaker, making it easier to land wires when the breaker is recessed or when multiple breakers are ganged side-by-side. The 6-unit pack covers a full complement of main and auxiliary terminals for a single 3-pole breaker. Mounting is straightforward — it snaps onto the front of the 3RV1 frame without tools.
