Breaking capacity sits at 100 kA at 240 V, 400 V, and 500 V AC, dropping to 8 kA at 690 V AC. That 100 kA figure at 400 V gives headroom for high-fault panels without cascading upstream breakers — a common requirement in industrial MCCs. No ground fault detection on this variant. ## Mounting and wiring — DIN rail, screw terminals Width is 45 mm, height 97 mm, depth 96 mm — fits a standard 45 mm-wide slot in the panel layout. Any mounting position allowed. Main circuit uses screw-type terminals accepting 2x (1 … 2.5 mm²) solid or stranded, and 2x (2.5 … 6 mm²) solid or stranded. AWG equivalent 2x (14 … 10) for the main contacts. Zero clearance needed at the back or sides — 0 mm backwards and 0 mm at the side.","metaTitle":"Siemens 3RV1021-1DA10-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-1DA10-ZX95 SIRIUS motor protection circuit breaker, 3.2 A continuous, CLASS 10 trip, 100 kA breaking at 400 V.
