DMC Range

The DMC range encompasses Termate’s traditional busbar supports.

DMC supports are available for Icw ratings up to 100 kA/1 s. These supports are compression moulded, unlike the black busbar supports which are injection moulded. There are a range of supports for different line centres and number of conductors.

  • Up to 100 kA/1 s fault rating

  • Body Material: Glass Reinforced Polyester DMC
  • Insert Material: Glass Reinforced Polyamide 6.6
  • Conductor Temp.: 140 °C
  • Flammability: UL 94 V-0
  • Glow Wire: 960 °C
  • Equipment Voltage, Ue: 1000 V AC, 1500 V DC
  • Insulation Voltage, Ui: 1000 V AC, 1500 V DC
  • Impulse Voltage, Uimp: 12 kV

In line with the requirements set out in IEC 61439 the supports are capable of carrying conductors operating at an average of 140 °C (max. 145 °C), the material for the supports having a satisfactory thermal index value established using methods similar to IEC 60216.

Selection 

For increased stock flexibility, the following range of supports are available in 2 separate parts, the Body and Insert. These parts are purchased separately and all inserts are interchangeable with all Body supports.

Please review the reference section below for your choice of support. For your ease of design. the associated .STEP file shows the combination of the Inserts and Body.
