The Siemens 3RV2917-5A is a SIRIUS connection plug designed for size S00 circuit breakers and contactors — the compact frame common across the SIRIUS 3RV and 3RT families. It uses a spring-type terminal, rated for 16 A, and ships in multi-unit packaging of 10 pieces.
The 16 A ampacity covers the load side of S00 breakers up to that current — typical for motor feeders and control transformers in the SIRIUS line. The spring terminal eliminates screw-torque checks during panel build; strip length and wire gauge follow the standard S00 spring-clamp spec (0.5–2.5 mm² solid/stranded, 4 mm² max). Dimensions of 80 mm depth, 45 mm width, and 40 mm height keep the plug within the same envelope as the S00 breaker, so no extra DIN-rail space is needed.
