The 110 V DC coil is the key fit parameter here — if your control voltage is 110 VDC, this is the variant you need. The DC coil holds in at 110 V nominal; inrush current peaks at 15 A.
This contactor is rated for AC-3 switching duty at up to 1,000 operations per hour, which covers standard motor starting and running for pumps, fans, and conveyors. AC-4 duty (plugging/reversing) is limited to 300 operations per hour — the higher electrical wear from inrush under reverse torque means you need to derate the mechanical life. Storage range extends to -55 to +80 °C. Screw terminals accept solid conductors: 2x (1 to 2.5 mm²) and 2x (2.5 to 10 mm²). Stranded connections are 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²). Main contacts have a tightening torque range of 16 to 8 Nm.
The auxiliary switch option (built-in) saves an extra module slot when you need feedback to the PLC.
