Description
Ensure your domestic hot water system’s electrical isolation point is both secure and compliant with the MK K370 WHI ‘Water Heater’ Fused Spur. Part of the market-leading Logic Plus collection, this switched connection unit is specifically designed for the dedicated control of heavy-duty water heaters, combining required circuit protection with clear, permanent labeling.
Reliability, Compliance & Clear Identification:
-
Permanent ‘WATER HEATER’ Marking: The faceplate is clearly and permanently marked with “WATER HEATER,” allowing users and maintenance engineers to instantly locate the dedicated isolation switch. Consequently, this prevents accidental shut-offs and ensures the installation remains intuitive, meeting professional and safety standards.
-
Integrated Safety & Local Protection: This unit includes a 13A fuse-link (BS 1362), which provides critical overcurrent protection for the heater. Furthermore, the double pole switch guarantees total electrical isolation for safe maintenance, while the fuse carrier can be locked in the open position to prevent unauthorized reactivation during servicing.
-
Integrated Bottom Flex Outlet: Designed with a discreet base-entry aperture, this unit allows the appliance’s flexible power cable to exit the wall neatly. Additionally, the patented screwless cord grip automatically secures the cable, providing superior strain relief and a tidy, professional finish.
The Logic Plus Advantage:
-
Antimicrobial Protection: Manufactured from a unique, high-grade thermoset material, the faceplate naturally inhibits the growth of bacteria (including MRSA, E. Coli, and Salmonella). This makes it the premier choice for installation in kitchens, airing cupboards, or utility areas.
-
Superior Switching & Visibility: The high-visibility red neon indicator is built into the rocker switch, providing a wide 175° field of vision. This allows you to confirm power status at a glance, from almost any angle.
