Product details

What ships in the carton — a complete reversing kit

The 3RA2315-8XB30-2AH0: This order code delivers a pre-assembled reversing contactor assembly built from two 3RT2015-2AH02 contactors, size S00. The kit includes both contactors, the mechanical interlock, and the wiring base — no loose parts to chase down. That means no screwdriver needed for the power or coil wiring — push the ferruled wire in and it locks.

Motor ratings and the AC-3 duty that matters

At 400 V AC-3, this assembly switches 3 kW (4.8 A). At 480 V it carries 4.8 A; at 600 V it carries 6.1 A. The horsepower equivalents run from 1.5 hp at 200/208 V up to 5 hp at 575/600 V. The AC-4 rating at 400 V is also 3 kW — this is the plugging / inching duty rating, so the assembly handles reversing starts without derating for the higher electrical wear of frequent reversals. The coil terminals are spring-type, same as the main circuit.

Mounting flexibility on the DIN rail

Dimensions are 90 mm wide, 84 mm high, 83 mm deep — the standard S00 footprint. Clearance around the assembly: 6 mm upwards, 6 mm downwards, 6 mm to the side, 6 mm forwards, 0 mm backwards (flush to the rail).

Lifecycle and compliance — active production, RoHS dated

Operating temperature range is -25…+60 °C; storage range is -55…+80 °C.
