What this contactor carries
The ABB AF26-22-00-11 is a 4-pole contactor from the AF26 family, rated at 45 A and 600 VAC. The coil accepts 20-60 VAC or 20-60 VDC, giving you a single part number that works across both AC and DC control circuits without a separate rectifier. The built-in auxiliary contacts are 2 NO and 2 NC, so you get feedback and interlock wiring without adding a side-mount block. Mounts on DIN rail, which means it clips into the standard 35 mm rail inside any control panel. No screws, no backplate drilling — just snap it on and wire the power and control terminals.
45 A is the thermal continuous current (Ith) at 600 VAC, handling resistive loads up to that level. The 4-pole configuration lets you switch three phases plus a neutral, or use the fourth pole as an early-make/late-break auxiliary. The 2 NO + 2 NC auxiliary set is already integrated — no separate add-on block needed for basic feedback or interlocking.
