Schneider Electric Square D NQ0DQ2 Main Breaker

Schneider Electric's Square D NQ0DQ2 Main Breaker Adapter Kit is a dedicated accessory that enables a main circuit breaker to be installed in Square D NQ panel interiors, converting a lug-only interior into a serviced main-disconnect configuration. Also cataloged as NQODQ2, the kit is designed for NQ lighting and appliance panelboards and supports field installation where a factory-installed main is not present. Because the kit's purpose is to accept a compatible main breaker, the exact amperage rating, voltage, and approved breaker family are determined by the main breaker you pair with it, rather than by the adapter itself. This accessory is part of Square D's family of panelboard options and follows Schneider Electric's design standards for compatibility and safe integration within NQ interiors. Ideal for upgrades to existing NQ panelboards where centralized disconnection is required or preferred, the NQ0DQ2/NQODQ2 kit provides a streamlined path to a compliant, single-location main disconnect without replacing the entire panel.
