The XT4NU3040FFF000XXX: The 20 A rating sets the maximum continuous load this switch can carry without derating — match it to the branch circuit's full-load amps, not the motor nameplate alone, to avoid nuisance tripping under sustained load. The 3-phase designation confirms it's built for three-wire power distribution, common in motor, pump, and conveyor feeds. The 2-pole configuration means it switches both line conductors, leaving the neutral uninterrupted — typical for single-phase loads derived from a 3-phase panel or for switching two legs of a delta system.
