Hazardous area lighting & power panelboards ATEX & IECEX for global Hazardous Area & Explosive Atmosphere Installations
Intro: Appleton NEC/CEC and ATEX/IECEx PlexPower Series Panelboards use circuit breaker modules that provide explosion proof protection for standard off-the-shelf breakers, eliminating the need for a heavy cast enclosure. Component level protection means the panelboard enclosure is lighter, more compact and easier to install.
Breakers can be easily replaced, upgraded or added in the hazardous area zone or workplace with no bolted cover to remove, no need for sealing or rewiring and no danger of compromising flamepath integrity. There’s never been a simpler, more versatile way to protect lighting, power and heat trace circuits in wet, weather exposed, corrosive or hazardous locations.
It’s been ten years ago since Appleton introduced their PlexPower™ line of hazardous location distribution boards – bringing the concept of component-level protection to North American markets governed by NEC and CEC standards. With new certifications for IECEx and ATEX installations, Appleton Group introduced the P-Series PlexPower distribution boards to the global marketplace.
P-Series PlexPower Easy To Install, Operate and Maintain.
AN INNOVATIVE WAY TO PROTECT
BREAKERS IN HAZARDOUS AREA LOCATIONS
For Zone 1 and Zone 2 (Gas) and Zone 21 and Zone 22 (Dust) explosive atmosphere applications, P-Series PlexPower distribution boards offer an innovative method for protecting power distribution, lighting and heat trace sytems. Appleton’s exclusive technology incorporates Labyrinth Joint Flamepaths into modular main and branch circuit breaker housings – allowing the use of standard, off-the-shelf circuit breakers that can be replaced in the field, instead of specialized, epoxy-encapsulated breakers.

This unique flameproof design offers many advantages. For example, the Appleton P-Series uses standard circuit breakers which are less expensive than sealed breakers and are easier to source and stock. The lightweight, corrosion-resistant polyester enclosure is easy to mount, and the door can be opened without needing to remove multiple bolts and without compromising the flameproof integrity of individual breaker housings.
Hazardous Area Industries & Applications
ATEX IECEx Panelboards are specified extensively in the following industry sectors:
PlexPower is engineered to solve operational problems, easily adapting to your installation needs while providing the flexibility you require to reconfigure electrical power circuits and increase capacity at any time.
Appleton P-Series PlexPower distribution boards are also designed to fit a user’s unique power requirements and installation footprint. The modular design allows multiple distribution panel boards to be coupled together horizontally or vertically, offering practically unlimited circuit configurations while adapting to the available space.
A hot-dip galvanized steel wall mounting frame is included with each distribution board, and an optional self-standing frame is available for floor mounting, with or without a canopy, making the P-Series PlexPower distribution board flexible to any installation requirements.
A 50 kA copper busbar simplifies wiring while providing robust, reliable connections in a compact space. Factory installed Increased Safety line and load terminations are sized to accommodate branch breakers up to 32 amps, so facilities can easily upgrade ampacity in the future without rewiring the distribution board. Optional removable gland plates can be punched or drilled in the field to accommodate cable or conduit entries.
