That means you're not piecing together the reversing pair and interlock separately; it arrives ready to wire into the panel. ## Motor ratings that govern the real load Rated 11 kW at 400 V AC-3 and 21 A at 480 V, this S0 reversing contactor handles standard three-phase induction motor reversing duty up to those breakpoints. At 690 V it still carries 11 kW, so it's not derated by voltage alone — the current limit is the constraint. For AC-4 duty (plugging / inching) at 400 V, the rating drops to 7.5 kW. If your application involves frequent reversing under load, size against the AC-4 figure, not the AC-3 one. The mechanical life is 10 million operating cycles typical, which is standard for the SIRIUS contactor family and sufficient for most conveyor, pump, and fan reversing applications. ## Mounting and wiring — panel fit without surprises The 90 mm width and 101 mm height fit the S0 footprint; depth is 107 mm. Clearance around the unit: 6 mm upwards, forwards, downwards, and to the sides, with 0 mm backwards (–) — so it can sit flush against the back panel. Coil terminals are screw-type. That covers the range from control wiring up to the main power feed for an 11 kW motor.","metaTitle":"Siemens 3RA2326-8XE30-1BB4 SIRIUS Reversing Contactor","metaDescription":"Siemens 3RA2326-8XE30-1BB4 SIRIUS reversing contactor assembly, S0 size, 24 VDC coil, 11 kW at 400 V AC-3.
