Type 2B Accessibility

Offers increased protection around the entire perimeter of the AR-JK, including instances when the low voltage compartment is open and under maintenance.

Insulated Main Bus

Insulated main bus prevents inadvertent contact with bus bars and isolates them to limit the spread of an arc blast.

Modular, Pre-Assembled Exhaust Plenum

Exhaust plenum channels fire, smoke, and debris from an arc fault out and away from personnel around the perimeter of the AR-JK MCC. The modular design enables the plenum to be installed facing the left, right or back depending on user requirements.

Advanced Pressure Relief System

Designed to redirect arc blasts safely, an internal venting system and ventilation flaps are utilized to manage internal pressure.

Reinforced Structural Design

Reinforced doors, sides and end covers increase the AR-JK’s ability to safely withstand an arc fault explosion.

Bolted Pressure Isolation Switch

Designed with a mechanical interlock between the contactor and the isolation switch prevents opening or closing of the isolation switch unless the main contactor is opened.
