Product details

The coil is rated 96-127 VAC at 50/60 Hz with screw-type terminals, and the main power circuit accepts stranded conductors from 16 to 70 mm². The contactor is fastened by screw fixing to a vertical mounting surface, rotatable ±90° and tiltable ±22.5°. Switching rates: 750 operations per hour for AC-1 and AC-3 duty, 400 for AC-2, and 130 for AC-4. The arcing time is 10-15 ms, and the mechanical life is typically 10,000,000 operations. MTBF is listed at 75 years.

Sizing and integration

Dimensions: 172 mm height, 120 mm width, 170 mm depth. The auxiliary switch is included (screw-type terminals). The contactor is designed for panel mounting with screw fixing, typical for SIRIUS S6 frame installations in motor control centers.

Switching performance

AC-1 maximum current at 750 ops/h for resistive loads. AC-3 motor switching at 750 ops/h. AC-4 (plugging/reversing) at 130 ops/h. The coil pick-up is 0.8 x rated voltage (76.8 V minimum), drop-out at 0.6 x rated voltage (57.6 V). Operate time 115-130 ms AC and DC; release time 115-130 ms. Auxiliary contact ratings: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V.
