It's a 3-pole device with screw-type terminals for main and auxiliary circuits, designed for protecting motor feeders against overload and short-circuit. The 12.5 A rating sets the thermal overload threshold. The breaker trips on overload per its Class 10 characteristic. Breaking capacity is 100 kA at 400 V AC, dropping to 42 kA at 500 V and 6 kA at 690 V. At 240 V it's also 100 kA. The 45 mm width (3-module) fits standard enclosure rail. Any mounting position allowed, with 0 mm clearance needed at the sides or rear — tight panel layouts are fine. Terminals accept 2x (1 to 2.5 mm²) solid or stranded, or 2x (2.5 to 6 mm²) — covers most motor feeder cables up to 6 mm². AWG equivalent 14 to 10. Screw-type terminals on main and aux circuits; no special tooling needed. Not for washdown environments. Shock rated 25g for 11 ms — survives typical shipping and panel vibration. RoHS compliance date marked 01.05.2012 — the part meets the EU RoHS substance restrictions as of that date. Surge voltage resistance rated 6000 V, which covers the impulse withstand for standard 400 V industrial installations. No ground fault detection on this variant.","metaTitle":"Siemens 3RV1021-1KA10-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-1KA10-ZW96 SIRIUS motor protection circuit breaker, 12.5 A continuous, 5.5 kW at 400 V, 100 kA breaking capacity.
