MCBs
MCBs (Miniature Circuit Breakers) provide essential protection for electrical circuits, automatically switching off in the event of overloads or short circuits.
Designed for domestic, commercial, and industrial use, they are a key safety component within consumer units and distribution boards.
Use cases include protecting lighting, socket, and appliance circuits to ensure reliable operation and compliance with the 18th Edition Wiring Regulations.
The benefits include enhanced safety, reduced risk of fire, and quick restoration compared to fuse-based systems.
YESSS stocks MCBs from trusted brands such as Hager, Schneider, FuseBox, and our exclusive ERiS brand ensuring long-lasting quality and compatibility.
Popular technical specifications include current ratings from 1A to 125A, single- and three-phase options, breaking capacities from 6kA to 70kA, and A, B, C, and D trip curve types.
For safe, compliant, and reliable protection, choose MCBs from YESSS Electrical.
