Breaking capacity is 100 kA at 240 V, 400 V, and 500 V, dropping to 10 kA at 690 V. Fuse backup ratings are specified: gL/gG 25 A at 400 V and 500 V, and gL/gG 20 A at 690 V. If you need to coordinate with upstream fuses for higher fault currents, those are the maximum fuse sizes the breaker is tested with. Clearance requirements: 50 mm upwards, 50 mm downwards, 30 mm at the side, 0 mm forwards and backwards — so it can sit flush against a backplate or enclosure wall. Dimensions are 97 mm deep, 45 mm wide, 106 mm high. No screw torque to verify — just strip to the right length and push in. ## Environmental and operational limits Maximum switching rate at AC-3 duty is 15 operations per hour — fine for occasional motor starts, not for high-cycling applications like rapid reversing or jogging.","metaTitle":"Siemens 3RV2011-1CA20 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2011-1CA20 SIRIUS motor protection circuit breaker, Class 10 trip, 100 kA breaking capacity at 400 V, screw/snap-on DIN rail mount.
