Its coil accepts 83-155 VAC at 50/60 Hz, drawing 3.5 VA holding power at both frequencies. Screw-type coil terminals and main contact screw terminals simplify wiring in the panel. Its S3 frame size (70 mm wide, 140 mm high, 152 mm deep) fits standard enclosure layouts.
Switching capacity and operating rates
Rated for AC-1 resistive loads at 900 operations per hour maximum, AC-3 motor switching at 850 ops/h, and AC-4 inching/plugging at 200 ops/h. The AC-3e rating matches the AC-3 figure at 850 ops/h. These duty-cycle limits determine how frequently the contactor can switch under load without exceeding thermal rise. Arcing time spans 10-20 ms, and the main contactor's mechanical life is typically 10 million operations. The auxiliary switch is included, with main contacts rated for 10 make/break cycles at rated current.
Wiring and environmental specs
Main circuit accepts solid conductors from 2.5 to 16 mm² or stranded from 6 to 70 mm². Auxiliary terminals accept 2x (0.5-1.5 mm²) solid/stranded or 2x (0.75-2.5 mm²). Clearances: 10 mm upward/downward, 20 mm forward, 10 mm at the side.
