Mounting is via the snap-on feature for 60 mm busbar systems, not DIN rail — this is a busbar-mount variant, so factor that into your panel layout. The mounting position is vertical only, and the degree of pollution rating is 3 (conductive pollution or dry non-conductive that becomes conductive), which is typical for industrial control panels without climate control. ## Power ratings across common voltages At 400 V, the motor power rating is 7,500 W (10 hp). At 460/480 V, the horsepower rating is 10 hp. At 575/600 V, it's also 10 hp. The current ratings at 480 V and 600 V are 14 A and 11 A respectively, so the limiting factor at higher voltages is the contactor's thermal capacity, not the voltage withstand. For 230 V single-phase or low-voltage three-phase, the rating is 2 hp at 230 V and 5 hp at 220/230 V three-phase. At 110/120 V, it's 1 hp — this covers control transformer-fed motor circuits in North American panels. This is fine for the 14 A max current — you'll typically land 1.5 mm² or 2.5 mm² motor leads. ## Physical fit and clearances Width is 45 mm, depth is 155.1 mm, height is 200 mm. Clearance requirements: 20 mm upwards, 10 mm downwards, 9 mm at the side. No forward or backward clearance is needed (0 mm each), so you can pack units tight front-to-back on the busbar. Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C. The -20 °C lower operating limit is worth noting for unheated warehouses or outdoor enclosures in cold climates. No official successor or cross-reference is needed — the part is current. The supplied contactor (3RT2018-1AK61) and link module (3RA1921-1DA00) are also active, so replacement modules are straightforward to source separately if needed.","metaTitle":"Siemens 3RA2110-4AD18-1AK6 SIRIUS Motor Starter, 45 mm","metaDescription":"Active-production Siemens SIRIUS 3RA2110-4AD18-1AK6 non-fused load feeder, size S00, direct starter, CLASS 10, 45 mm wide, 690 V rated.
