Clearance: 6 mm upwards, forwards, downwards, and to the side; 0 mm backwards (flush to the rail). Solid wire capacity: 2x (1…2.5 mm²) and 2x (2.5…10 mm²). Stranded: 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²). Coil terminals are also screw-type. These are standard panel terminations — no special crimp tooling needed. ## Ratings and environmental limits Rated operational power at 400 V is 18.5 kW; at 500 V and 690 V it also carries 18.5 kW. At 480 V the rated current is 34 A; at 600 V it is 27 A. Horsepower ratings: 10 hp at 220/230 V, 25 hp at 460/480 V and at 575/600 V. Coil voltage: 110 V at 50 Hz, 120 V at 60 Hz. Shock resistance: 13.5g / 5 ms and 8.3g / 10 ms (AC), 15g / 5 ms and 10g / 10 ms (DC).","metaTitle":"Siemens SIRIUS 3RA2328-8XB30-1AK6 Reversing Contactor Assemb","metaDescription":"Siemens SIRIUS reversing contactor assembly, size S0, rated 18.5 kW at 400 V AC-3.
