The AC-3 motor-switching rating goes up to 690 V, and the maximum operating frequency is 15 operations per hour, so this is a protection device, not a cycling switch. Mounts via screw fixing — no DIN-rail clip on this frame size. Clearance requirements: 0 mm backwards and 0 mm at the side, so you can pack it tight against the back panel and adjacent devices. Overall dimensions are 205 mm high, 140 mm wide, 103.5 mm deep. Main circuit terminals are screw-type, same for the auxiliary/control circuit. The breaker accepts auxiliary switch add-ons (product extension auxiliary switch: Yes), though this base unit ships with zero built-in auxiliary contacts — 0 NO, 0 NC, 0 changeover. If you need status feedback, order the auxiliary switch block separately and snap it on. IP20 on the front, finger-safe touch protection per the standard. Shock resistance is 12g for 11 ms. Rated voltage range is 20 to 690 V AC, surge voltage resistance rated at 8,000 V.","metaTitle":"Siemens 3RV1373-7GN10 SIRIUS MCCB, 400 A, 120 kA at 400 V","metaDescription":"Siemens SIRIUS 3RV1373-7GN10 molded-case circuit breaker, 400 A continuous, 120 kA breaking capacity at 400 V AC.
