The Siemens 3RV1917-5A is a cable connector for Size S00 circuit breakers, fitted with spring-type terminals and supplied in multi-unit packaging. This part is the wiring-side interface for the 3RV1 family — it connects the load-side conductors to the breaker without needing screwdriver torque, which speeds panel wiring on repetitive builds.
The spring-type terminal accepts solid or ferruled stranded conductors without a screw clamp — strip length and wire gauge follow the same range as the 3RV1 breaker terminal specs. Multi-unit packaging means the connector ships in bulk qty per pack, not individually bagged, which suits panel shops running multiple identical breaker positions.
