Hylec-APL fused terminal blocks help to keep the lights on...

Most large lighting installations involve multiple fittings being supplied by a single circuit protection device. However, if a fault occurs within one of the individual fittings it will cause the circuit protection device to trip and the remaining units on that circuit will lose power. Losing so many lights at once may cause significant inconvenience, but it can also make identifying the location of the fault a lengthy task as all of the connections need to be checked until the fault is found.

By using fused terminal blocks from Hylec-APL, it is possible to provide individual fittings with properly discriminated protection, meaning 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 having a 5×20mm fuse-holder, rated for 13A, 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 20A. The terminals offer IP2X finger protection and can accept conductors up to 4mm2 without wire protectors.
