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.","metaTitle":"Siemens 3RA2315-8XB30-2AH0 SIRIUS Reversing Contactor","metaDescription":"Siemens 3RA2315-8XB30-2AH0 SIRIUS reversing contactor assembly, size S00, 3 kW at 400 V AC-3.
