DBBS Range

The DBBS range offers a flexible solution for small power distribution applications.

The DBBS range is capable of Icw ratings of up to 50 kA/1 s.

They offer easy connection to moulded case circuit breakers. The intelligent design accommodates 20, 25, 30×10 mm, and 20, 25×5 mm conductors in one support. There is a 3 phase and a 3 phase + neutral version available.

  • Up to 50 kA/1 s fault rating
  • Suitable for 5 conductor sizes

3 phase or 3 phase + Neutral

  • Material: Glass Reinforced Polyamide 6.6
  • Conductor Temp: 140 °C
  • Flammability: UL 94 V-0
  • Glow Wire: 960 °C
  • Termate Icw Rating:

25 kA for 3 s @ 315 mm support spacing

50 kA for 1 s @ 220 mm support spacing

  • Equipment Voltage, Ue: 690 V AC, 690 V DC
  • Insulation Voltage, Ui: 690 V AC, 690 V DC
  • Impulse Voltage, Uimp: 6 kV

In line With the limits set out in IEC 61439, insulating components in contact with conductors may be required to continuously operate at an average of 140 °C (max. 145 °C).

This range of products meets the requirement, the material for them being assigned thermal class F established using methods similar to IEC 60085
