Their product portfolio is designed for reliability, ease of installation, and long-term durability, ensuring full compliance with current 18th Edition Regulations and relevant British Standards.
At the core of their offerings are metal consumer units, which are noted for their fire-resistant properties and aesthetic design, making them suitable for various interior styles. These units are complemented by a wide selection of essential protection devices, including Residual Current Devices (RCDs), Residual Current Breakers with Overcurrent (RCBOs), and Arc Fault Detection Devices (AFDDs). These components are critical for enhancing electrical safety, providing necessary protection against faults and fire hazards.
For more demanding applications, MK Circuit Protection offers TP&N (Triple Pole and Neutral) distribution boards, which are robust solutions ideal for environments such as office buildings, shopping malls, and healthcare facilities. The brand also caters to the growing demand for sustainable infrastructure with dedicated Garage and EV (Electric Vehicle) charger boards, which come in various configurations, including options with built-in surge protection and RCBOs to ensure stable, fast, and safe charging setups.
In addition to their primary distribution and protection hardware, the company provides various accessories to support complete system installations, such as busbar covers, terminal bars, and locking devices. Their commitment to quality is underscored by a robust warranty policy, offering a 5-year guarantee on SPD and AFDD ranges and a 10-year guarantee on the remainder of their product line. By combining modern manufacturing processes with in-house design, MK Circuit Protection delivers versatile, high-quality solutions that remain a preferred choice for electricians and building managers seeking both safety and operational longevity.
