What is the British Standard number for MCBs?

Explanation:
MCBs are protective devices designed to interrupt current when a fault or overload occurs, and the standard that specifies their design, performance, and testing is BS 60898. This British standard (historically) covers miniature circuit breakers used in low-voltage installations and is harmonized with the international EN 60898-1, ensuring compatibility and safety across manufacturers and products used in domestic circuits. The other standards listed pertain to different protective devices, such as fuses, and do not apply to MCBs. So BS 60898 is the correct one for MCBs.
