The ABB AF26-30-00-41 is a 3-pole IEC contactor on the AF26 frame, rated for 45 A continuous current and a 600 V maximum insulation voltage. The 45 A rating is the AC-1 thermal current (Ith) — the continuous resistive load it can carry without derating. For motor duty (AC-3), the actual switching current will be lower, typically around 18–22 A for a standard 3-phase induction motor, so size the contactor to the motor full-load amps, not the 45 A headline figure. The coil is 60 VAC/VDC, which means it pulls in on either supply type at that nominal voltage; the pickup threshold is typically around 48 V and dropout below 18 V, so verify your control voltage stays above the pickup minimum during brownout conditions.
Deployment context — panel integration
In a control panel, this contactor occupies roughly 45 mm of rail width. The 3-pole power terminals accept up to 16 mm² cable; the coil terminals are spring-cage for 0.2–2.5 mm².
