For motor duty, the contactor is rated 15 hp at 460/480 V and 20 hp at 575/600 V.
The 24 V DC coil draws a holding current determined by the contactor's magnetic circuit; the pickup voltage threshold is 0.7 times the rated value, meaning the coil must see at least about 16.8 V DC to pull in reliably. Dropout typically occurs below 0.1 to 0.2 times rated, so a saggy 24 V bus won't cause nuisance dropouts unless it collapses below roughly 4 V. Auxiliary contact ratings are given for DC switching: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. These are the DC-13 inductive load limits — useful for pilot duty on PLC inputs or relay coils in the same panel. The impulse withstand voltage of the main circuit is 6 kV, which covers typical 400 V distribution systems with overvoltage category III. The contactor is rated for operation up to 2,000 m altitude without derating.
The 45 mm width (size S0) fits a standard 45 mm DIN-rail slot. Depth is 100 mm, height 119 mm — verify clearance to the gland plate or enclosure door. Screw terminals accept 2x (0.25...2.5 mm²) solid or stranded, 2x (1...2.5 mm²) and 2x (2.5...6 mm²), with a maximum of 2x 10 mm² per clamp. The contactor supports side-by-side mounting without derating, so multiple units can pack tightly on the rail.
