The overload release and short-circuit trip are both electronic, with an adjustable trip class of CLASS 10, 20, or 30. That means you can match the thermal curve to the motor's starting profile — CLASS 10 for high-inertia loads like crushers, CLASS 20 for standard pumps and fans, CLASS 30 for long-start conveyors. Fastens via screw fixing — no DIN-rail clip on this frame size. Dimensions are 210 mm wide by 268 mm high by 103.5 mm deep, with zero clearance required at the back or sides, so it can sit tight against the panel backplane or adjacent devices. Rated for 15 operations per hour maximum at AC-3 duty — this is a protection device, not a switching contactor. The surge voltage resistance is 8 kV, so it handles transient spikes on industrial mains without nuisance tripping. Shock resistance is 12g for 11 ms, acceptable for most machine-mounted applications.","metaTitle":"Siemens 3RV1083-7JL10 SIRIUS MCCB, 800 A, 355 kW, 100 kA","metaDescription":"Siemens SIRIUS 3RV1083-7JL10 molded-case circuit breaker for motor protection. 800 A continuous, 355 kW at 400 V, 100 kA SCCR.
