Rated coil voltage is 110 V AC, with a pickup threshold of 0.8 x rated value and a dropout at 1.1 x full-scale value — meaning the coil reliably pulls in above 88 V and releases above 121 V, a standard margin for industrial AC control circuits.
Switching duty and thermal limits
Maximum switching frequency depends on the duty category: 1 000 operations per hour at AC-1 (resistive), 750/h at AC-2 and AC-3 (motor starting/running), and 250/h at AC-4 (plugging/inching). The AC-3e rating also allows 750/h. These limits govern the contactor's thermal endurance — exceeding them shortens life or risks contact welding.
Panel integration and clearances
Dimensions: 85 mm high, 45 mm wide, 151 mm deep. These spacings ensure adequate ventilation and arc-quenching volume — critical when grouping multiple contactors on a DIN rail. This allows panel builders to orient the contactor for best wire routing without derating, as long as the clearance envelope is respected.
Wiring and auxiliary contacts
Main contact terminals accept solid or stranded wire from 1 to 10 mm², with dual-wire capability: 2 x (0.5 to 1.5 mm²) or 2 x (0.75 to 2.5 mm²).
