The interrupting rating is a flat 100 kA across all common industrial voltages (240 V, 400 V, 500 V, 690 V AC), so it handles high available fault current without cascading upstream breakers. The 45 mm width keeps the footprint tight in a multi-device motor control center. Screw-type terminals on the main circuit accept stranded conductors up to 2x 6 mm² or solid up to 2x 2.5 mm², so it handles standard motor feeder cables without adapters. Auxiliary contacts are transverse design, with space for one block. Clearances: zero mm required at the rear or sides, so you can butt-mount these against other devices on the rail. Front face is IP20 — finger-safe for panel access, but keep it inside an enclosure. Shock rated at 25g for 11 ms, which covers most conveyor and pump vibration environments.","metaTitle":"Siemens 3RV1021-0JA15-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-0JA15-ZX95 SIRIUS motor protection circuit breaker.
