MCBs

What are MCBs?

Miniature Circuit Breakers (MCBs) are low capacity reusable electromechanical devices that are designed to protect an electrical circuit from overloading or short circuits. Utilised in a wide range of industrial and domestic applications, MCBs will typically be found in a distribution board providing protection to electrical components within each separate circuit.

What types of MCB are available?

There are three types of MCBs that are commonly used:

Type B MCBs - Used in domestic circuit protection where there is little need for surge permission.

Type C MCBs - Used in commercial and light industrial environments which may feature large fluorescent lighting circuits, transformers and IT equipment such as servers, PCs and printers.

Type D MCBs - Used in heavy industrial facilities such as factories using large winding motors, X-ray machines or compressors.

There are also Types A, K and Z MCBs available.

Type A and Type Z MCBS are highly sensitive to short circuit and better suited to semiconductor devices, while Type K MCBs trip when the current reaches eight to 12 times the maximum, so are better suited to industrial motor applications.
