The Eaton A26-30-01-81 is a 3-pole, non-reversing across-the-line contactor rated at 45 A with a 24 V AC coil and one normally closed auxiliary contact.
The 45 A rating is the continuous current-carrying capacity for the main poles under typical AC-1 resistive load. For motor duty (AC-3), expect derating — the 45 A frame typically handles a 20–25 A motor full-load current, but always verify against the motor nameplate FLA. The 24 V AC coil is a common control voltage in North American and some European panels; it draws a modest inrush and hold VA, compatible with standard 24 VAC control transformers.
Deployment context
The 1 NC auxiliary contact is wired into the control circuit for status feedback or interlocking. Non-reversing means it switches power in one direction only — no electrical or mechanical interlock for reversing duty.
