The ABB A26-30-01 is a power contactor in the block contactor form factor, rated for 45 A thermal current (Ith) and 40 A at 600 V AC under UL/CSA general-use conditions. Its AC-3 motor-switching capability is 6.5 kW at 230 V, with a rated insulation voltage of 1000 V. The ring-tongue terminals suit panel wiring where secure, vibration-resistant connections are required — common in motor control centers and distribution panels.
The 45 A Ith is the continuous current the contactor can carry in open air — this governs the main power path sizing. The 40 A at 600 V AC UL/CSA rating is the general-use resistive load limit; for motor loads, the AC-3 rating of 6.5 kW at 230 V is the figure that decides whether this contactor handles a given three-phase induction motor. Ring-tongue terminals require a ring lug on each wire — not a spring-cage or screw-clamp interface, so verify the panel's termination method before specifying.
