The A26-22-00-81: 35 A at 600 VAC is the continuous current rating through each pole — sized for lighting banks, resistive heater loads, or non-motor switching where the inrush stays under that figure. The 4-pole configuration lets it switch three phases plus a neutral in a single device, common for 3-phase lighting distribution or multi-circuit control. 24 VAC control coil keeps the contactor compatible with standard building-automation control transformers.
Surface-mounted in a panel — the contactor body bolts directly to the backplate, with line and load terminations on the top and bottom. Used for centralized switching of lighting circuits in commercial or industrial buildings where a contactor panel replaces multiple individual relays.
