Product details

It accepts a coil supply of 175-280 V AC/DC, making it a single-device solution for panels that run mixed AC/DC control voltages without needing a separate coil rectifier. Inrush current peaks at 65 A, which is typical for this frame size — factor that into your DC supply if you're running a bank of contactors off a single 24 VDC bus.

Dimensions are 140 mm high, 96 mm wide, and 152 mm deep — the depth is the dimension that often surprises panel builders when the contactor is mounted sideways or near a gland plate.

Main contact terminals accept stranded wire from 6 to 70 mm² — that covers everything from a 4 AWG feed to a 1/0 AWG for high-current motor circuits. The coil terminals are screw-type and accept solid or stranded wire: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). The auxiliary switch is included, with contact ratings ranging from 10 A at 24 V down to 0.3 A at 220 V — check the specific load type (AC-15, DC-13) against your PLC input card.
