The terminal accepts solid conductors from 2.5 to 16 mm² and stranded conductors from 2.5 to 25 mm², so it handles both panel wire and heavier feeder cable. It's IP20 on the front, which is standard for enclosed panel gear — no washdown rating, no outdoor use without a cabinet. ## Lifecycle reality — phased out, successor named This part is flagged as a phased-out product. The official Siemens successor is the 3RV2925-5EB, which is the preferred replacement for the SIRIUS 3RV2 series. If you're holding a BOM with 3RV1925-5EB, the drop-in cross is that newer order code — same function, same footprint for the 3RV2 breaker sizes S00 and S0. If the buyer prefers the current-production successor, we can source that as well. The 63 A ampacity maximum tells you this terminal won't be the bottleneck in a feeder rated up to that current — it's sized for the larger S0 breaker frame. The compact dimensions — 32 mm deep, 44 mm wide, 44.5 mm high — let it mount directly on the breaker top without stealing extra DIN rail space; you're not adding a separate terminal block row. The screw-type terminals accept a wide wire range: solid up to 16 mm², stranded up to 25 mm², and with core-end processing up to 16 mm². That covers most motor feeder cables up to about 50 A continuous. The storage temperature range of -50 to +80 °C and operating range of -20 to +60 °C are typical for panel-mounted gear in unconditioned plant environments. This terminal is designed to snap onto the top of a 3RV2 circuit breaker — no DIN rail mounting of its own; it rides on the breaker. The fork-shaped connections on the original 3RV1925-5EB mate with the breaker's line-side terminals. If you're replacing an older 3RV1 breaker with a 3RV2, the 3RV2925-5EB successor is the correct match.","metaTitle":"Siemens 3RV1925-5EB SIRIUS Three-Phase Feeder Terminal, 63 A","metaDescription":"Siemens 3RV1925-5EB SIRIUS three-phase feeder terminal for 3RV2 breakers sizes S00/S0.
