Fused terminal blocks help to keep the lights on.

14 May 2014

A new range of fused terminal blocks from Hylec-APL can offer localised protection within an electrical circuit.


Designed for a wide range of uses, especially lighting applications, the terminal blocks ensure that a circuit fault in one fitting does not affect others on the same circuit, which can keep the majority of the lights on and make it easier to locate the fault.

The Hylec-APL range uses high quality materials and offers features such as an integral spare fuse carrier to make installation and maintenance procedures as simple as possible.

By using fused terminal blocks, it's possible to provide individual fittings with properly discriminated protection so that, in the event of a fault, only a single light will go out. The terminal blocks are available in a variety of configurations, with one to five poles, making them suitable even for emergency light fittings; each has a 5 x 20mm fuse-holder, rated for 13 amps, with an integrated spare fuse carrier.

The terminal blocks can be specified with or without earth terminals and wire protectors depending on customer requirements. They are made from UL94-V0 flame retardant polyamide for the terminal moulding and the connectors are nickel plated brass and rated to 20 amps. The terminals offer IP2X finger protection and can accept conductors up to 4mm2 without wire protectors.
