Features

Featuring a generous 30-circuit capability within a compact footprint, this interior allows commercial electricians and property managers to maximize branch circuit density. It handles a diverse mix of single-pole and multi-pole breakers, making it perfect for dedicated workshop power feeds, multi-family sub-panels, or localized commercial retail lighting distribution.
Shipped with factory-installed 200-amp main lugs for straightforward sub-panel applications, this chassis is fully convertible to a main circuit breaker panelboard using simple, field-installable conversion kits. This versatility saves valuable project time by adapting instantly to shifting design-build requirements without forcing you to source an entirely new enclosure.
Engineered exclusively for the legendary Square DTM QOTM plug-on circuit breaker lineup, this panelboard guarantees a low-resistance, rock-solid physical and electrical connection. It seamlessly accommodates standard thermal-magnetic breakers, dual-function CAFCI/GFCI safety devices, and surge protective modules, providing your installation with ultimate system-wide reliability and safety.
Built to handle a 3-phase, 3-wire or 4-wire, 240V AC maximum electrical configuration, this load center effortlessly balances heavy commercial power loads. It provides clean, stable power delivery to multi-phase motors, commercial kitchen equipment, and HVAC compressors while maintaining strict compliance with local electrical safety codes.
