The magnet coil uses spring-type terminals, while the main and auxiliary power circuits accept solid or stranded conductors from 1 to 10 mm², or 2x (0.5 to 2.5 mm²) for the auxiliary contacts.
Auxiliary Contact Ratings and Switching Frequency
The built-in auxiliary switch is rated for 10 A at 24 V, 2 A at 48 or 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 0.6 A at 440 V — these are the make/break capacities for the control circuit, not the main pole current. The main contact configuration is 18 normally open plus 8 normally closed, giving flexibility for interlocking or feedback wiring without an add-on block. Maximum switching frequency depends on duty: 1,000 cycles per hour at AC-1 (resistive), 750 cycles per hour at AC-2 and AC-3 (motor starting/running), and 250 cycles per hour at AC-4 (plugging/inching). The AC-3e rating mirrors the AC-3 figure at 750 cycles per hour.
