Compared to the 3RV2021-1FA15, the 3RV1021-1EA10-ZX95 is the lower-current sibling — 4 A versus the 2021's higher rating. Both share the SIRIUS form factor and screw-terminal design, so they swap into the same DIN-rail footprint without rewiring the panel. Wire the main circuit with 1 to 6 mm² solid or stranded conductors (AWG 14-10), and the auxiliary contacts with the same range. The screw terminals accept ferruled stranded wire with core-end processing. No backward clearance needed at the rear — 0 mm — so it sits flush against the backplane. Breaking capacity hits 100 kA at 240 V, 400 V, and 500 V AC, then drops to 6 kA at 690 V AC. Shock resistance rated at 25g for 11 ms, so it holds up in high-vibration environments like conveyor drives or compressor skids.","metaTitle":"Siemens 3RV1021-1EA10-ZX95 SIRIUS Motor Protection Breaker,","metaDescription":"Siemens 3RV1021-1EA10-ZX95 SIRIUS motor protection circuit breaker, 4 A continuous, 1.5 kW at 400 V, Class 10 trip, 100 kA breaking capacity, screw terminals, DIN rail mount.
