Eaton Critical Load Panel / Load Center, Surface Mount – BRP12B100R

Product Overview

The Eaton BRP12B100R is a Type BR plug-on neutral main breaker loadcenter in a rainproof outdoor enclosure. It distributes 120/240 V single-phase power to branch circuits and is commonly used as a critical-loads or backup subpanel when you need a compact outdoor-rated panel for essential circuits.

This unit uses Eaton Type BR 1-inch breakers and a plug-on neutral design that can reduce neutral pigtail clutter in the wiring gutters. NEMA 3R means the enclosure is rainproof for outdoor wall mounting (still keep openings and knockouts sealed per code and the installation instructions).
