The 3RV2011-1CA20: Trip Class 10 means it will trip within 10 seconds at 7.2× the thermal setting — standard for protecting standard induction motors against locked-rotor conditions without nuisance tripping on normal starts. 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.
