MK’s New Masterseal PlusTM is an Open and Shut Case

MK Electric is replacing its award-winning Masterseal range with a collection of enhanced IP-rated products called Masterseal Plus™. 

Scientifically sealed and tested by MK well in excess of British Standards, new Masterseal Plus™ protects the electrical supply in the harshest of environments. As with its predecessor, Masterseal Plus™ is specifically developed for use in both outdoor and indoor environments, and where wiring devices and accessories would be at risk from penetration by dust or water.

With a superb IP rating of IP66, Masterseal Plus™ is dust-tight to any ingress, offers complete protection against contact, and high pressure water jets directed against the enclosure from any direction won’t have any harmful effects.

Masterseal Plus™ sockets are unique in that they can be used with virtually any standard 13A plug, allowing a safe power connection for any appliance. Added features to the new range also include a seating spout to house moulded on plugs, an improved lid catch for easy opening, as well as a fixed gasket and rear drill holes to ensure faster and easier installation. The range comes in grey, white or black.

The new Masterseal Plus™ enclosures have been specifically designed to house Logic Plus switch and socket variants, thus conferring all the features and benefits from this industry-leading range. For example, terminal screws are backed out and captive, and terminals are upwards facing to make installation easier; as do printed terminal markings. For safety, there is the IEC 3mm minimum gap across the switch break; while all standard sockets feature MK’s pioneering three-pin operated ‘child resistant shutter system’, designed to inhibit access to the electricity supply unless all 3 pins of a standard British 13A plug are in position. The Masterseal Plus™ range is guaranteed for an industry-leading 20 years (10 for electronic products).

Indoor and outdoor applications to which new Masterseal Plus™ is perfectly suited include factories, laboratories, swimming pools and changing rooms, commercial kitchens, industrial units, warehousing and clean rooms.


For less demanding applications, where a good degree of ingress protection is required, but not to the high specification of an IP66 rated product; the company has introduced MK Shield™. MK Shield™ is rated to IP56, and available in grey, white or with a clear lid. The range is suitable for use in stadia, small to medium-sized commercial premises, arcades, parks and for operating appliances such as vending machines and larger gardening equipment. MK Shield™ is guaranteed for 10 years.

Finally, MK Splashguard™ – rated IP55 – completes the company’s portfolio of IP solutions, and is designed for occasional domestic use such as with garden equipment, providing protection to power supplied in damp or dusty environments.
