Meter Frame & Panel Options

There are two standard options available for the metering section:-

  • EMF 015CTP - 600h x 610w x 150d (Panel - 600h x 600w x 6d)
  • EMF 017CTP - 900h x 610w x 150d (Panel - 900h x 600w x 6d)

With both options the panels are pre-drilled specifically for Current Transformer metering as per local standards which includes:-

  • Meter position
  • Test block
  • Fuse box (including 3mm tap for direct fixing of cover)

Each option includes an earth stud and lug. Both items can also be found in the Frame & Panels section on the Products page.

Current Transformer Chassis

Electrical Meter Frames currently have two options for the Current Transformer Chassis (Gear Tray):-

  • 200A (nominal load) -
    • Ordering part number - EMF200
    • Fault Current: NATA tested - 20.5kA for 1 second
    • Dimensions: 420 x 504 (incl tags) x 91

  • 400A (nominal load) -
    • Ordering part number - EMF400
    • Fault Current: NATA tested - 32kA for 1 second
    • Dimensions: 420 x 534 (incl tags) x 103

Note: Due to the increased stresses on the 400A chassis during fault conditions, the following additional strengthening features are included for the EMF400 as determined through rigorous testing.

  • High grade insulator standoffs
  • High tensile bolts for all current carrying components
  • Reinforced channel fitted to bottom fixing of insulators to reduce tray deformation.

Current Transformer Chamber

A standalone chamber desined specifically to house either the EMF200 or the EMF400 chassis.

  • Dimensions - 500h x 720w x 310d
  • Neutral Busbar with M10 cable bolts fitted
  • 3 x 32A HRC CT potential fuse holders and cartridges fitted
  • Removable door
  • Adjustable chrome pintle hinges
  • recessed door handle
  • Welded M8 chassis mounting studs and earth stud
  • Door stay
  • Tamper seal and industry lock facility
