Any mounting position is permitted. Clearance requirements: 70 mm upward and downward, 30 mm to the side, zero forward or backward. Main circuit terminals accept 1 to 10 mm² solid or stranded, up to 2×10 mm²; screwdriver shaft diameter 5 to 6 mm, Pozidriv size 2 tip. ## Transformer-duty design Unlike a standard motor-protective circuit breaker, this unit is engineered for transformer inrush and overload characteristics per UL 489. The gG fuse coordination values at 400 V are 50 A, at 500 V 40 A, and at 690 V 35 A — these define the maximum backup fuse for the breaker's short-circuit rating. No ground-fault or phase-failure detection built in; external protection is needed for those functions.","metaTitle":"Siemens 3RV2811-1GD10 SIRIUS Circuit Breaker, 100 kA at 400","metaDescription":"Siemens 3RV2811-1GD10 SIRIUS circuit breaker, size S00, 100 kA breaking capacity at 400 V AC.
