It is rated for AC-4 duty at 8.5 A at 400 V, which covers the demanding inrush and plugging/reversing cycles of squirrel-cage motors. The coil is 24 VDC, with an integrated varistor surge suppressor across the coil terminals — no external snubber needed for DC switching transients. The main circuit uses screw-type terminals accepting 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid/stranded conductors — typical for control panel wiring. The auxiliary contact block is rated for DC switching: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V — these are the make/break limits for DC loads, which are more restrictive than AC due to arc extinction.
Integration Notes
The contactor is rated for 50/60 Hz operation with a voltage tolerance of 0.8 to 1.1 times rated at 50 Hz and 0.85 to 1.1 at 60 Hz — the coil will hold in across typical line variations. For short-circuit protection, the manufacturer specifies a gL/gG fuse rated at 20 A for type 2 coordination (no welding of contacts under fault). Electrical life will be lower and depends on the switched current and duty cycle.
