The S12 frame and 70-240 mm² stranded cable capacity suit high-current feeders. The 10 000 000 typical mechanical cycles support long service life. Operate time is 80-100 ms on both AC and DC, and arcing time runs 10-15 ms. That is typical for a contactor this size — the arc chute clears fast enough for most motor starting duty, but if you are switching highly inductive loads (large DC solenoids, transformer primaries) verify the breaking capacity against your fault current. Screw fixing through a single 11 mm hole. Coil pick-up at 0.8 of rated voltage.
