Martindale Electric LOK6 Series Instruction Manual

LOK6 is a lock off device for individual Red Spot fuse holder bases
up to 100A and other similar designs following removal of the fuse
carrier. LOK6W has been designed to fit Henley and Lucy Service
Cut Outs and is also suitable for larger Red Spot holders rated at
63A and 100A. LOK6-200 is for Red Spot holders rated at 200A
and 400A.
Many Red Spot style fuse holders, still in widespread use today,
are made of brittle materials that can be fractured easily by the
sharp grub screw found in conventional MCB / Fuse lock-off devices.
The LOK6 Series uses an effective clamp system to grip the wall
of the fuse holder base without risk of damage. The clamp system
accommodates wall thicknesses from 2mm to 5mm with ease.
The device is clamped adjacent to the terminal at one end of the
fuse holder, rendering it safe against accidental finger access. For
added safety, the design includes an integral sliding cover which can
be adjusted according to the fuse size/rating to reduce accidental
finger access at the far end of the fuse holder base.
