  1. Rugged Termination Each circuit breaker housing connects to the panelboard through Increased Safety line and load terminations for unyielding performance through years of heavy vibrations and shocks.
  2. Venting Plate  Unique design of breaker housing allows safe heat dissipation, enabling breakers to maintain their rated amperage while eliminating nuisance tripping.
  3. Flameproof Enclosure Housing  Labyrinth joint construction maintains hazardous location rating while allowing easy disassembly for servicing breakers.
  4. Field Replaceable Breaker  Standard, off-the-shelf circuit breakers are easy to obtain and reduce inventory costs and downtime

 

 

Materials

Enclosures: Glass reinforced plastic
Gasket: Silicone
Cover screws: Stainless steel
Nameplates: Stainless steel or laminated plastic (different colours available on special request).

Only PlexPower panelboards feature circuit breaker housings with a flameproof labyrinth joint, eliminating the need for expensive epoxy sealed breakers that are difficult to source and stock. PlexPower panelboards are easy to configure and upgrade as needed, with modular components that can be coupled together to suit your footprint and branch circuit requirements.

Features include:

  • External actuation of mains breaker – simplifies disconnect while maintaining enclosure integrity
  • External actuation of branch breakers through a weatherproof window – enables simple operation of branch circuits
  • Accepts multiple lockouts – helps ensure workplace safety
  • Tough polyester construction – provides a lifetime of durable, corrosion resistant service
