The coil is 24 VDC, pulling 3.3 W on close and holding at the same 3.3 W — steady-state dissipation is low, so heat buildup in a crowded enclosure isn't a concern. The contactor is rated for 10 A at 24 V (AC-12), 6 A at 230 V, and in AC-2 duty at 400 V it handles 3 kW. For tougher AC-4 reversing or inching, it's rated 6.5 A at 400 V. That means it's sized for small-to-medium motor loads — pumps, fans, conveyors — up to about 4 kW at 690 V.
Terminals and wiring
The solid-wire capacity is 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and max 2x (0.75 to 4 mm²) — also listed in AWG as 2x (20–16), 2x (18–14), and 1x 12. That covers most control and power wiring you'll find in a panel. The auxiliary contact block is a single NO (1 NO), which is enough for a feedback loop or a basic interlock.
Environmental limits
Maximum altitude is 2000 m — fine for most sites; if you're above that, you'll need to derate or pick a different contactor.
