Its electronic overload and short-circuit trip give you adjustable trip class — choose CLASS 10, 20, or 30 depending on the motor's thermal tolerance and starting profile. CLASS 10 is tight for high-inertia loads; CLASS 30 buys you more headroom for long acceleration times. Breaking capacity runs 120 kA at 400 V AC, 100 kA at 240 V, 85 kA at 500 V, and 70 kA at 690 V — enough for high-fault utility feeds without cascading upstream. Mounting is screw fixing in any position, with a 140 mm width and 103.5 mm depth that fits standard panel layouts. ## Integration notes Panel builders: the 140 mm width and 103.5 mm depth fit a standard DIN-rail or backplate layout; screw fixing is required (no snap-on). The IP20 front allows direct panel mounting without additional covers. Auxiliary switch extension is supported (product extension auxiliary switch: Yes), so you can add status feedback for PLC or HMI. No ground fault detection built in, but phase failure detection is standard.","metaTitle":"Siemens 3RV1073-7GL10 SIRIUS MCCB, 400A, 120kA at 400V","metaDescription":"Siemens 3RV1073-7GL10 SIRIUS molded-case circuit breaker, 400 A continuous, 120 kA breaking at 400 V AC.
