Square D 8903L1R Lighting Contactor

The Square D 8903L1R Lighting Contactor Power Pole Adder is the official right-side extension for 8903L/LX lighting contactors, adding one electrical pole to a base six-pole assembly to yield eight poles. As a 1-pole power pole adder, it is designed to be used with its matching left-side partner 8903L1L to configure an eight-pole 8903L/LX contactor. This accessory enables expanded load switching in lighting-control circuits without replacing the main contactor, and it shares the same coil drive as the base assembly. In typical 8903L/LX installations, the eight-pole arrangement supports up to 30 A per pole and up to 600 V, with coil voltage commonly 110/120 VAC at 50/60 Hz for the related 8903L/LX devices. The 8903L/LX family is a multipole lighting contactor lineup intended for commercial and industrial lighting control, and the L1R (right-side) add-on is paired with L1L to achieve eight poles on a single control. Follow all applicable electrical codes and safety practices when wiring and configuring power-pole adders with 8903L/LX contactors.
