8903LO60V02 - Square D Lighting Contactor

When you’re managing a large lighting system, you don’t just need a contactor—you need one that performs day in and day out without surprises. The 8903LO60V02 electrically held lighting contactor is built for exactly that kind of reliability. Designed for commercial and industrial lighting control, this unit gives you consistent switching power for fluorescent and tungsten lighting loads, while keeping maintenance simple and downtime to a minimum.

What makes this model especially practical is its flexibility. You’re not locked into one configuration—the contacts can be converted from normally open (NO) to normally closed (NC) right in the field, and the coil is interchangeable, so you can adapt it to different system requirements without replacing the entire unit. That’s the kind of feature that saves time, money, and headaches over the long haul.

With a 6-pole design and electrically held operation, this contactor is ideal for applications where lighting needs to stay on as long as power is applied—think warehouses, commercial buildings, and large-scale facilities. It’s straightforward, dependable, and built for professionals who don’t have time to babysit their equipment.
