EFEN LV Horizontal Fuse Switch Disconnects

The best of both worlds with EFEN SILAS and IN Series

  • Size 00, 1, 2, 3 and 4A for 160 A to 1,600 A
  • Cable covers provided with all disconnects
  • Fully compliant with IEC 60947 Part 1 and Part 3


Horizontal fuse-switch-disconnects provide an alternative mounting and connection method to vertical disconnects, for example for single circuit supplies and for the safe and cost effective upgrade or replacement of earlier generations of fuse switches.

The EFEN SILAS range has been used successfully in the New Zealand for 30+ years and is now complemented by the EFEN IN series.

Both the SILAS and IN series use the widely available and economic DIN blade fuse cartridges, and offer an excellent level of operator safety thanks to their AC22B switching capacity.

Both may be used in AC or DC applications, as specified by their ratings.

The SILAS range is designed for independent mounting for single switch protection applications by virtue of its terminal covers. These features are ideally suited to solar applications or wherever battery protection is required in an internal installation.

SILAS is also suitable for multiple feeder mounting on busbars with ratings from 160 A to 630 A.

The EFEN IN series of switches is available from 160 to 1,600 A and is a more compact design. Cable covers are supplied: these can be removed for use in applications where a protective enclosure is used. Its compact size makes the IN ideal for network pillar applications.

Sizes 00, 1, 2 and 3 of the IN series and sizes 1, 2 and 3 of the SILAS series have the added advantage of phase protection barriers moulded into the base.
