Rated for use up to 690 V, its breaking capacity is 100 kA at 240 V, 400 V, and 500 V AC, dropping to 6 kA at 690 V. At 400 V it is rated for 1.5 kW motor load, which is the typical sizing for a small pump or fan motor. It includes phase failure detection, which is critical for preventing single-phasing damage on three-phase motors. No ground fault detection is built in — that would require an add-on module or separate GFCI. Accepts solid or stranded conductors: 2x (1 … 2.5 mm²) and 2x (2.5 … 6 mm²), or AWG 14–10. The dual-wire capacity per terminal is useful for daisy-chaining control power or looping through the line side. Dimensions: 96 mm deep, 97 mm tall. Zero clearance required at the back or sides, so it fits tight against the backplane or adjacent devices. Shock rated at 25g / 11 ms. Surge voltage resistance at 6 000 V. Power dissipation is 7.25 W total in hot operating state (2.4 W per pole). RoHS compliance date is 01.05.2012.","metaTitle":"Siemens 3RV1021-1FA10-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-1FA10-ZW97 SIRIUS motor protection circuit breaker, 5 A continuous, CLASS 10 trip, 100 kA breaking at 400 V.
