Connections, Spare Covers, CTs & Other Accessories

Hiko designed covers and connections for EFEN E3 vertical disconnects

  • Connection tags for up to 3x 630 mm² cables per phase
  • V-clamps for cable connection without compression crimping
  • Current transformers for 250 to 800 A

Hiko provides a range of accessories to make the latest generation of EFEN E3 vertical fuse switch disconnectors even more versatile.

Connections

Connection plates have been specially designed to enable the connection of large cross section cables and multiple cables. These are typically ordered with the EFEN E3 disconnector as a complete assembly. The “compact single” connection is available as a retrofit kit.

Side entry tags are available for either the left or the right- hand side of the EFEN E3 disconnector.

Hiko also engineers bespoke connection solutions for individual customer requirements. 

Spare Covers

Connection plates are provided complete with covers; spare covers are available if required.

Current Transformers

The EFEN E3 disconnector product line includes a specially designed range of Class 1 CT’s that fit neatly onto the busbar connection tags, without increasing external dimensions.

Other Accessories

The range of accessories available also includes: V-clamps, for cable connection without compression crimping; mounting brackets to provide attachment points on the side of the EFEN E3 disconnector; handle clips to identify a particular circuit such as the incomer; and CT cable covers, to protect the special CT wiring behind the disconnector.
