The surge voltage resistance of 6000 V gives it a rated impulse withstand that matches typical IEC 60947-2 coordination levels for distribution boards — so it can handle the transient spikes from nearby switching without nuisance tripping or damage. The screw and snap-on mounting onto 35 mm DIN rail per EN 50022 is the same footprint used by the SIRIUS contactor family (e.g., 3RT1016-1AR11, 3RT1016-1AG61, 3RT1023-1AL20). So if you're replacing a contactor with a motor-protective circuit breaker or adding one upstream, it clips onto the same rail without extra brackets. The 10.6 cm x 5.5 cm x 10.7 cm dimensions leave room for side-by-side mounting with adjacent devices — no special spacing required for standard coordination.","metaTitle":"Siemens 3RV1021-0EA10 Circuit Breaker, 690 V, IP20, DIN Rail","metaDescription":"Siemens 3RV1021-0EA10 circuit breaker, 690 V operating voltage, IP20, screw and snap-on DIN-rail mount.
