Arc Resistant Switchgear

Medium Voltage Arc Resistant Switchgear

Arc Resistant Switchgear

For complete protection for surrounding operators and personnel RIC Power Corp offers Arc Resistant Switchgear. Combining high strength steel, a compartmentalized and reinforced structure, and plenum and exhaust chute, Arc Resistant Switchgear contains and protects from potentially hazardous arcing events.


Now available: 25kV, 25kA Arc Resistant Switchgear.

In May, 2020, RIC Power Corp. passed destructive testing to certify its 25kV Arc Resistant Type 2B design. We are happy to now provide a complete offering of 5/15/25kV Arc Resistant Switchgear.

Prioritizes Safety & Protection

Significantly reinforced steel structure offers protection from arc fault events.

Plenum & Exhaust Chute

In arc fault situation the specifically designed plenum and exhaust chute redirects hazardous materials away from surrounding area.

Fully Customizable

Engineers utilize 3D modelling to create an arc resistant switchgear that fits the specific application.

Features & Specifications


  • Primary circuit components are compartmentalized by the use of grounded metal barriers incorporated into the enclosure structural configuration.
  • Front accessible draw out breakers, line and/or load side CT’s, draw out PT’s and draw out CPT’s.
  • Front viewing windows.
  • Polyolefin heat shrunk busbar c/w booted bus connections.
  • Busbar support structure configured for optimum heat dissipation and strength under fault conditions.
  • Ground ball studs where applicable for safe maintenance practices.
  • Door interlocks ensure that withdrawable components are only rackable with door closed and latched.
  • Plenum and exhaust chute designed to be installed in facility with minimal ceiling clearance.
  • Rear infrared viewing ports (optional).
