MK Essentials

MK Sentry

The introduction of the 18th Edition of the IET Wiring Regulations BS 7671:2018, see’s a requirement for overvoltage (surge) protection in some installations. In addition, the responsibility for the selection of appropriate RCDs falls to the designer/installer.

MK’s Sentry range now includes a selection of pre-populated Consumer Units featuring Surge Protection Devices (SPDs), as well as individual SPDs for those designing and building bespoke boards, to enable customers to meet the new requirements. The range of RCD devices now includes Type A RCD devices, alongside Type AC RCD devices, giving installers a choice of products to meet the requirements of residential applications.

 

Surge Protection Devices (SPDs) have been tested and approved for use in the Sentry consumer unit system. The SPD consists of a base unit and two surge cartridges, one each for Line and Neutral circuits. When a surge is detected the indicator on the front of the cartridge which operates on overvoltage will change to Red. This indicates that the cartridge has prevented damage to the power system and will need replacing. Surge cartridges are easy to install, thanks to keyed locator pins which make it impossible to position incorrectly.

Type A RCD devices give installers a choice of products to meet the requirements of residential applications. Suitable for type A and AC applications, faults in AC and DC currents will be detected. Type A RCDs are suitable for resistive capacitive induction loads and single phase loads with electronic components.


New sockets designed



Be Supercharged

The MK Sentry metal consumer unit has a stronger, more robust design with a top hinged door that prevents the door being left open after use, which could lead to a possible fire risk. The units also include sealed side holes to ensure total containment, reducing the available space for fire to escape.

A supporting Din Rail ‘T’ Bar supports the weight of the devices without twisting or bowing, and three additional extra large feed holes provide greater flexibility of wiring, especially in retrofit installations.

The products also benefit from continual earthing which means you only need to earth once via the base as the door is earthed through the hinges.
