Its reversing design integrates two contactors interlocked for forward/reverse motor rotation, with a thermal bimetallic overload relay providing Class 10 trip protection. Rated for AC-3 duty up to 690 V, this starter delivers 11 kW at 400 V, 15 kW at 500 V, and 22.2 A at 480 V. Horsepower ratings span 3 hp at 230 V to 20 hp at 575/600 V, covering a wide range of three-phase motor loads. ## Panel integration and mounting constraints Snap-on fastening on a 35 mm DIN rail in vertical mounting position. The unit occupies 90 mm width, 120 mm depth, and 265 mm height. Clearance requirements: 30 mm upward, 10 mm forward, 10 mm downward, 9 mm at the side, and 0 mm backward — critical for enclosure layout and heat dissipation. Operating temperature range -20 to +60 °C, with storage limits from -50 to +80 °C. The degree of pollution is 3, meaning the starter is suitable for industrial environments with conductive pollution or dry non-conductive pollution that becomes conductive due to condensation. ## Lifecycle and sourcing posture Compliance documentation includes RoHS compliance with substance prohibitance date 03/01/2017. The product carries the SIRIUS brand designation and is designed as a Type of Assignment 2 load feeder.","metaTitle":"Siemens 3RA2220-4DB27-0AP6 SIRIUS Reversing Motor Starter","metaDescription":"Siemens 3RA2220-4DB27-0AP6 SIRIUS non-fused reversing motor starter, size S0.
