The 100 kA rating at 400 V covers most industrial panel bus conditions, so downstream coordination is straightforward. Any mounting position is allowed, with 0 mm clearance required at the rear and sides. ## Key protection features Ground fault detection is not included, so a separate ground-fault relay is needed for that function. The auxiliary switch option is available for remote status indication. Finger-safe touch protection is standard on the front terminals. Shock rated at 25 g for 11 ms. The RoHS compliance date is May 1, 2012, covering substance prohibitions under EU Directive 2011/65/EU.","metaTitle":"Siemens 3RV1021-1GA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1021-1GA10 SIRIUS motor protection circuit breaker, 6.3 A continuous, CLASS 10 trip, 100 kA breaking at 400 V.
