The screw-type terminals accept solid or stranded conductors: 2x (1...2.5 mm²) and 2x (2.5...6 mm²) per pole, with AWG equivalents of 2x (14...10). Zero clearance is required at the back and sides — 0 mm backwards and 0 mm at the side — so it can be packed tight against adjacent devices on the rail without derating. The auxiliary switch option (product extension auxiliary switch: Yes) means you can add a remote status contact without extra wiring to the main circuit. The 25 A continuous rating and 11 kW motor rating make it a direct fit for motor branch circuits feeding pumps, fans, or small conveyors up to that power level.","metaTitle":"Siemens 3RV1021-4DA10-ZW98 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-4DA10-ZW98 motor protection circuit breaker, 25 A continuous, 11 kW at 400 V, 50 kA breaking capacity, Class 10 trip, IP20 front.
