Phase-failure detection is built in, so it trips on a lost phase before single-phasing cooks the winding. It is designed for motor protection, not general branch-circuit protection — the CLASS 10 curve matches motor start-up inrush, not resistive loads. Width is 45 mm, height 97 mm, depth 96 mm; backwards clearance is 0 mm, side clearance 0 mm, so it packs tight against adjacent devices in the row. Screw-type terminals on both main and auxiliary circuits accept solid or stranded conductors: 2x (1... 2.5 mm²) and 2x (2.5... 6 mm²) per clamp, with fine-stranded wire requiring a ferrule. AWG equivalents are 2x (14... 10). ## Operating conditions and approvals Runs at -20 °C to +60 °C ambient during operation; storage and transport tolerate -50 °C to +80 °C. Shock resistance is 25g for 11 ms. Surge voltage withstand is 6 000 V. The part carries a substance prohibition date of 01.05.2012, aligning with RoHS and REACH compliance milestones. Power dissipation at rated load is 7.25 W total, 2.4 W per pole — small enough that no special ventilation is needed in a standard enclosure.","metaTitle":"Siemens 3RV1021-1GA10-ZW95 SIRIUS Motor Protection CB, 6.3 A","metaDescription":"Siemens 3RV1021-1GA10-ZW95 SIRIUS motor protection circuit breaker, 6.3 A continuous, CLASS 10 trip, 100 kA at 400 V, phase-failure detection.
