The coil is rated 24 VDC with a pickup threshold of 0.8 x rated value. Dropout timing on DC is 38 to 65 ms, and arcing time runs 10 to 15 ms.
The auxiliary switch is present, and the main contact wire range accepts solid 0.5 to 4 mm² and stranded 0.5 to 4 mm², with combinations up to 2x 4 mm² or 2x (0.5 to 1.5 mm²). Switching frequency limits depend on duty: AC-1 (resistive) allows up to 1,000 operations per hour; AC-3 (motor starting) and AC-3e both cap at 750 ops/h; AC-4 (plugging/inching) drops to 250 ops/h. These are the thermal limits of the contactor — exceeding them shortens life or causes welding. Rated operational current varies by voltage: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. At 230 V the rating is 1 hp. These are the contact ratings for the auxiliary or main circuit depending on configuration. Mechanical life is typical 30 million operations. This affects how close you can pack adjacent devices on the DIN rail without derating.
