ATEX & IECEx Panelboard For Global Hazardous Area Installations.

T&D thank Appleton for contributing the following Guest Blog.

It’s been less than five years 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.

Appleton PowerPlex IECEx ATEX Certified PanelboardsFor Zone 1 and 2 – 21 and 22 applications, P-Series PlexPower distribution boards offer an innovative method for protecting power distribution, lighting and heat trace circuits. Appleton’s exclusive technology incorporates Labyrinth Joint Flamepaths into modular main and branch circuit breaker housings – allowing the use of standard, off-the-shelf 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.

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 panels 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.

Operating the distribution board is simple, with external actuation of the main breaker, as well as branch breakers through a weatherproof window. Breakers can be locked in the On or Off position, with the ability to use multiple lockouts on the main breaker for extra security. Plus, Appleton’s P-Series PlexPower is the only IECEx and ATEX certified distribution board that allows user’s to reconfigure or replace breakers in the field anytime, with no specialized components required.

P-Series PlexPower distribution boards are available in six standard configurations, fulfilling a majority of field requirements. Panelboards can also be coupled together to create over 300 configurations, as well as custom configurations to suit any specific requirements.

Main breaker and branch breakers can also be configured, including:

  • Exclusive 250 amps Mains MCCB and choice of 250 amps disconnect. Both offerings are available in 2-, 3-, and 4-poles, 40 through 250 amps in progression up to 690 volts
  • 1-, 2-, 3-, 4-poles, 1-pole+neutral, with and without GFI (10, 30, 100 and 300mA) sensitivity, with and without auxiliary contacts
  • Current ratings ranging from 0.5 amps through 63 amps
  • Voltage available in 220-240/380-415, 440 volts
  • KAIC ratings based on coordination study using proper mains and branch breakers
