Dimensions are 152 mm deep by 150 mm wide by 160 mm high — a compact footprint for a reversing pair, leaving room alongside for overload relays or busbars. ## Ratings that matter for the motor load At 400 V AC-3/AC-3e duty, the assembly switches 45 kW at up to 850 operations per hour — that cycle rate suits frequent reversing applications like conveyors, hoists, or positioning tables. Rated for shock loads up to 10.6 g / 5 ms and 6.3 g / 10 ms, so it holds up on mobile equipment or near heavy-impact machinery.","metaTitle":"Siemens 3RA2346-8XB30-1AG2 SIRIUS Reversing Contactor","metaDescription":"Siemens SIRIUS reversing contactor assembly 3RA2346-8XB30-1AG2, 45 kW at 400 V, size S3.
