Typical applications include:

  • LV switchboards with busbars
  • Electrical distribution panels
  • Industrial power distribution
  • Busbar trunking and panel assemblies

Key benefits:

  • Enables residual-current sensing — The core balance transformer provides the sensing element for a compatible Broyce Type A earth leakage relay.
  • Fits the chosen conductor arrangement — The 160 x 470mm (Order Code: 99-1909) aperture accommodates a suitable group of circuit conductors, subject to physical fit and installation design.
  • Supports a defined relay setting — The documented minimum ELR IΔn setting of 1A helps specify a suitable relay configuration.
  • Simplifies mechanical installation — Corner fixing holes provides a documented fixing approach for the installation.
