Product details

Reversing contactor assembly — size S00, 3 kW at 400 V

The 3RA2315-8XB30-1AF0: It ships with two 3RT2015-1AF02 contactors pre-assembled on a mechanical interlock base — no field wiring of the reversing interlock required.

Motor ratings and switching duty

Horsepower ratings span 1.5 hp at 200/208 V up to 5 hp at 575/600 V — covers common North American and IEC motor frames in a single unit. Maximum switching frequency is 750 operations per hour in AC-3 and AC-3e duty — sufficient for most reversing applications like conveyors, hoists, and door operators. Mechanical life of the contactor is 10 million operations typical.

Dimensions are 90 mm wide × 68 mm high × 73 mm deep — fits standard S00 footprint. Shock resistance rated at 10.5 g / 5 ms and 6.6 g / 10 ms on both AC and DC axes.
