Screw-type terminals on the main circuit accept 2x (1…2.5 mm²) solid or 2x (2.5…6 mm²) stranded, with AWG equivalents at 2x (14…10). ## Installation & Integration Zero clearance required at the sides or rear — 0 mm backwards and 0 mm at the side — so it fits tight panel layouts. Shock rated at 25g for 11 ms. Mounting position is unrestricted. ## Coordination & Ratings The interrupting capacity steps down with voltage: 100 kA at 240 V AC, 50 kA at 400 V, 10 kA at 500 V, and 4 kA at 690 V. Rated impulse withstand voltage is 6 kV. Mechanical endurance on the main contacts is 100,000 operations typical. An auxiliary switch is included as standard (0 auxiliary contacts for the main circuit — the auxiliary switch is a separate integrated unit). The maximum switching frequency at AC-3 duty is 15 operations per hour.","metaTitle":"Siemens 3RV1021-4DA10-ZX95 SIRIUS Motor Protection CB, 25A,","metaDescription":"Siemens 3RV1021-4DA10-ZX95 SIRIUS motor protection circuit breaker, 25 A continuous, 11 kW at 400 V, Class 10 trip, 50 kA SCCR at 400 V.
