MCBs/RCBOs Circuit Breakers

Both the Industrial Distribution Boards and the Domestic Consumer Units require MCBs and RCBOs - the circuit breakers, which you can find in this section.

This page lists distribution boards from other manufacturers, as well as DIN rail-mounted MCBs and RCBOs for use in consumer units.

Please choose the manufacturer of the consumer unit/MCB you have or require, and based on this, you can add the desired MCBs in the basket to purchase them.

Select the subcategory you require to find the MCB you need from BG MCBs, MK MCBs, MEM MemShield MCBs, Hager MCBs, Wylex MCBs, Schneider MCBs, Crabtree MCBs, and Merlin Gerin MCBs.

At Sparks we hold large stocks of MCBs and RCBOs and circuit breakers; you can purchase them online for delivery or in-store pick-up if you are local to us in North London.

For any enquiries related to the MCBs, Circuit Breakers, RCBOs, etc do not hesitate to contact us.
