13A Connection Units, 20A Switches and Flex Outlets

Description

A range of 13A fused connection units and 20A DP switches designed for the

connection of refrigerators, water heaters, central heating boilers and other fixed

appliances.

The ranges are designed for ease of installation and have the advantageous design

features of the MK range of wiring devices.

Neon indicators

Products are available with Neon indicators included in the rockers of the switched

connection units. In the case of unswitched units, they are positioned centrally and

uppermost on the face plate. Neon indicators are integrally wired into the product

and do not require separate connection when installing. The design gives 175°

visibility in the horizontal and vertical planes.

Fuse carriers

These are captive and are opened by a fast acting, screwdriver operated worm

drive for ease of replacement. A tamper-proof version is also available.

Fuse carriers can be locked open using a padlock, List No. K2000.

Flex outlets

Bottom outlet types are supplied with blanking plug allowing use where the bottom

outlet is not required.

The products are equipped with very strong, push-fit nylon cord grips making

installation safe, quick and easy.

Flex outlet plate

An unfused flex outlet with cord grip and 3 pairs of terminals.

Installation

Products must be installed in accordance with current IET Regulations.

rating.
