Rated switching capacity at 24 V is 10 A, dropping to 2 A at 48 V and 60 V, 1 A at 110 V, and 0.3 A at 220 V — these are the make/break currents for resistive loads (AC-1) or motor loads (AC-3) at those voltages. At 400 V it handles 3 A; at 440 V, 0.2 A. The 230 V rating of 1 hp tells you the motor size it can switch at that voltage. Maximum switching rates: 1000 ops/h for AC-1 (resistive), 750 ops/h for AC-2 and AC-3 (motor starting), and 250 ops/h for AC-4 (plugging/inching). The arcing time is 10 to 15 ms, and the solid/stranded wire range is 0.5 to 4 mm² (single or 2x 0.5-1.5 mm², 2x 0.75-2.5 mm², 2x 4 mm²).
Mounting position is standing on a horizontal surface.
