The 3RV1021-1GA10-ZX95: 6.3 A continuous current with CLASS 10 trip means the breaker protects motors that draw up to that full-load current and trips within 10 seconds at 7.2× rated current — matching standard IEC starting profiles for pumps, fans, and compressors. The 100 kA SCCR at 400 V is the maximum fault current the device can safely interrupt without upstream backup; at 690 V the rating drops to 6 kA, so verify available fault current if wiring into a 690 V system. Rated power at 400 V is 2.2 kW for a standard 4-pole motor, which gives a quick motor-sizing reference for panel builders.
Width is 45 mm, height 97 mm, depth 96 mm — standard SIRIUS 3RV1 footprint. Mounting position any; no derating needed for sideways or inverted install. Screw terminals for main and auxiliary circuits accept 2× (1…2.5 mm²) solid or stranded, or 2× (2.5…6 mm²) — covers common motor feeder wire sizes. IP20 on the front; suitable for enclosed panels.
