Ground fault detection is not included (no); that requires an external module or a separate ground-fault relay. Each pole accepts 2 conductors: solid or stranded 1 … 2.5 mm², plus a second pair of 2.5 … 6 mm². For AWG, that's 2x (14 … 10) for the main contacts. The dual-terminal design allows daisy-chaining power through the breaker without extra terminal blocks — common in motor starter wiring where the line side feeds the contactor coil. Shock resistance is rated at 25 g for 11 ms, typical for industrial vibration environments.","metaTitle":"Siemens 3RV1021-4DA10-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-4DA10-ZW96 SIRIUS motor protection circuit breaker, 25 A continuous, CLASS 10 trip, 50 kA at 400 V AC.
