Square D 8903L3R Contactor Power Pole Adder

Product Description

The SQUARE D 8903L3R is a contactor power pole adder designed to expand the switching capacity of compatible contactor assemblies. This accessory adds an additional power pole to an existing contactor, increasing the number of load circuits that can be controlled without replacing the base unit. It is used in motor control, HVAC, and industrial load-switching applications where additional pole capacity is required. Licensed electricians and HVAC controls technicians are the primary installers. The unit measures 3.7 inches in length, 3 inches in width, and 2.2 inches in height, and weighs 0.52 pounds.

This power pole adder is suited for commercial and light industrial electrical panel and load-center installations where an existing SQUARE D contactor requires additional switching poles. Typical applications include multi-phase motor starters, large HVAC equipment contactors, and control panel assemblies that need expanded circuit capacity. It ships as a single-unit package and is intended for direct integration with a compatible base contactor.
