Product details

Its AC-3 duty rating permits up to 850 switching cycles per hour at full motor current — a figure that sets the cycle budget for starting and stopping induction motors under load. An auxiliary switch is built in, so feedback to the PLC or safety circuit is available without an external add-on block.

Solid conductors from 2.5 to 16 mm² and stranded conductors up to 70 mm² are accepted at the screw-type coil terminals. The unit occupies 70 mm width, 140 mm height, and 152 mm depth.
