4-pole 22 A contactor with 24 VDC coil
The J7KNG22424D: The coil is 24 VDC, which means it pulls in cleanly on a standard 24 VDC control bus — no AC ripple to filter, and no hold-in dropout from a sagging rectified supply.
Mounting and termination options
Terminations are screw terminals, field-serviceable with a standard Pozidriv or slotted driver. The 4-pole, 4NO contact arrangement gives you four independent power paths in one package, useful for switching a three-phase motor plus a neutral or auxiliary load without an extra contactor block.
DC switching and voltage limits
Rated for 2.5 A DC switching current at 220 V DC — the DC rating is lower than the AC-3 figure because DC arcs sustain longer. If your load is DC, budget for the 2.5 A ceiling, not the 22 A AC number. The 15 HP rating (presumably at 460/480 V three-phase) gives a quick motor-size reference for North American panel specs, though the 11 kW / 22 A AC-3 figures are the primary selection criteria.
