Description

Square D™ NQ Main Circuit Breaker Interiors, NQMB2Q, Main Circuit Breaker Adapter Kit fo 225 A. Product has certifications in cULus.

Features

Designed specifically for 225-amp maximum NQ lighting and appliance panelboards, this main breaker conversion kit ensures a precise, factory-grade fit. It allows commercial electricians to seamlessly upgrade main lug only (MLO) enclosures to a main breaker configuration on-site, avoiding the long lead times and heavy costs associated with ordering a completely new custom electrical distribution panel.
This mounting hardware is precision-engineered to properly anchor standard Square D Q-frame circuit breakers, including 2-pole and 3-pole QDL, QGL, and QJL models. By securely fastening the heavy-duty main breaker directly to the panel's internal bus, it guarantees a rigid, fault-resistant power connection that safely handles high-capacity commercial loads without causing dangerous mechanical stress.
Shipping complete with all necessary mounting brackets, dead-front cover plates, phase connectors, and fastening screws, this OEM installation kit eliminates frustrating mid-job delays. The intuitive, bolt-on design drastically reduces expensive facility downtime, allowing maintenance crews and panel builders to execute rapid, code-compliant power upgrades.
As a genuine Schneider Electric / Square D component, utilizing this specific kit maintains the strict UL Listing and CSA certification of your existing NQ electrical enclosure. Trusting factory-authorized conversion hardware ensures your modified switchgear remains fully compliant with the National Electrical Code (NEC), guaranteeing a smooth pass during rigorous municipal building inspections.
