It accepts solid or stranded conductors from 2.5 to 25 mm² (AWG 12 to 4) and is rated for a maximum ampacity of 63 A, with an insulation voltage of 690 V AC at pollution degree 3. The screw-type terminals are sized for the main current circuit of the breaker, making this a panel-integration component rather than a standalone protective device. ## Physical fit and wiring constraints The terminal measures 44 mm wide by 24 mm high by 25 mm deep — a compact footprint that sits directly on the busbar feed point of the S00 or S0 breaker. The 25 mm depth is the key dimension for panel clearance: it projects less than a typical contactor or breaker depth, so it fits into shallow gland-plate zones or behind a DIN-rail mounted assembly. Conductor range covers 2.5 to 25 mm² solid or stranded, and 4 to 16 mm² finely stranded with ferrule. The single-conductor entry per phase (1x) means you cannot double-feed the same terminal; plan for a separate distribution block if you need to split the feed.","metaTitle":"Siemens 3RV1915-5A SIRIUS 3-Phase Supply Terminal, 63 A, S00","metaDescription":"Siemens 3RV1915-5A SIRIUS 3-phase supply terminal for S00/S0 circuit breakers. 63 A ampacity, 690 V insulation, screw terminals.
