57_AppletonP-SeriesPowerPlex_zps2d1926ffAppleton Electric’s PowerPlex P-Series panelboard is engineered for applications in potentially explosive environments and eliminates the need to install barrier glands or conduit seals.

They’re ATEX/IECEx certified to Zone 1 – 2 and 21 – 22 requirements for indoor and outdoor protection and electrical circuit control in hazardous industrial locations, including petrochemical plants and refineries.

Fibreglass reinforced polyester housings and stainless steel hardware also qualifies the panelboards for wet, corrosive areas, such as water treatment centres.

Unlike epoxy-encapsulated versions, flameproof enclosures allow breakers to be replaced in the field. The panelboard’s busbar design and modular configuration makes installation flexible and maintenance easy.

A 50-kA busbar system provides more robust, reliable and efficient electrical connections in a compact space, joining powermains through a hard-copper connection. Factory installed line and load connections increase breaker ampacity without rewiring.

Six standard configurations allow nearly 300 design possibilities between 40 to 250 A with 3- for 4-pole mains MCCB for primary protection.

With the flameproof labyrinth joint, standard off-the-shelf breakers can be used rather than costly, specialized sealed breakers, thus minimizing maintenance and inventory costs.

Appleton Electric is a manufacturer of electrical supply products based in Rosemont, Ill.
