LMT & LMVP Arc Proof Door

Existing switchboards have no internal arc withstand, human presence in front of the live switchboard is unavoidable.

Safety for operators, staff and visitors in front of the existing switchboard is achievable and racking through a closed arc-proof door is essential.

Benefits of retrofitting an arc proof door:

  • Provides safety for staff
  • Includes racking through closed door
  • Quick installation
  • Can be fitted to LMT1 and LMT2
  • Strengthens the front of the switchboard
  • Allows the breaker to be in Busbar earth position with the door closed
  • Tested to IEC62271-200 for 25kA for 1s
