Eaton PRL-2A Panelboard

The Eaton PRL-2A Panelboard functions as a dedicated distribution center for commercial electrical infrastructure rated for 100 amps at 480Y/277 volts. Designed with a three-pole, four-wire topology, the unit distributes single-phase 277-volt and three-phase 480-volt power simultaneously across connected branch circuits within light-commercial buildings. Being configured as a Main Lug Only (MLO) assembly means the housing does not contain a main circuit breaker, necessitating external overcurrent protection from the incoming service conductors before power enters the bus bars. This configuration supports projects where centralized utility metering or service disconnect switches provide the necessary safety cutoff points upstream to simplify the load center layout. Qualified electricians select this model for office complexes, schools, and retail sites that require efficient zone protections without managing redundant main breaker components inside the enclosure.
