Clearance distances: 10 mm upwards, forwards, downwards, and to the side; 0 mm backwards — the back of the assembly can sit flush against the panel. ## Duty ratings and thermal limits for motor switching Rated for 850 switching operations per hour maximum in AC-3 and AC-3e duty — this is the mechanical limit for the reversing interlock, not a thermal derating.","metaTitle":"Siemens 3RA2346-8XE30-1NB3 Reversing Contactor Assembly","metaDescription":"Siemens SIRIUS reversing contactor assembly 3RA2346-8XE30-1NB3, 45 kW at 400 V AC-3, 75 hp at 460 V.
