Moulded case circuit breakers ( MCCBs) have a very similar function to MCBs but they also have a higher capacity. MCBs are all sub-100-amp devices and are designed for low voltage circuits, so their trip curves cannot be adjusted. By contrast, MCCBs feature adjustable trip characteristics, which means that they can be used with higher voltages – as much as 2,500 in some instances. What is the Difference Between MCBs and ELCBs? Any delay in carrying out your instructions for any reason whatsoever, including failure of operational sys-tems or interweb network; To test an MCB after installation, you will need a suitable portable voltage meter from a reputable manufacturer. Electricians also recommend manually inspecting the switching mechanism of MCBs before installation; typically, a greater degree of pressure is needed to open and close more reliable models. Can You Mix MCBs?

Residual current devices ( RCDs) are a different form of electrical safety equipment. While MCBs have a general function, RCDs are specifically built to protect against the frequently fatal risk of electrocution from touching exposed wires or incorrectly earthed cables. They operate directly within electrical circuits to detect faults and cut off potentially hazardous currents.From time to time we may advertise our own products and MCB Internet Banking Services, and those of other subsidiary companies in the MCB Bank, through the MCB Internet Banking Service.

However, mixing brands in the same installation is not recommended as it makes testing less reliable and can invalidate warranties and installation guarantees.
