Relays have a wide range of application in industry.Even with the advent of electronic control such as PLC and other solid state devices such as thyristors,the electromechanical relay still retain a high level of acceptance.

We can found relay in every where such as control panel,equipment and machinery.It is common use for automation and motor control application.

The reason for this is that for simple types of control,relay offer a cost effective solution.They are available in a large range of configurations from small of only 10mm in length with multiple contact pair for data communication,to large relay called contactor for carrying heavy current loads in applications such as switching 3 phase motors. read more

Molded Case Circuit Breaker

What is MCCB ( Molded Case Circuit Breaker ) ?

It is a mechanical device ( BS 4752 ) to be used to connect and disconnect the circuit in normal and abnormal.Current rate for regular MCCB up to 3000 ampere.

It is only available in a 3 pole only, usually for a system that has a high ampere ratings in three ( 3 ) phase systems.For those who have ampere ratings than 400 ampere, the safety interlock system is prepared for security purposes because the current system are high.

There are two ( 2 ) types of MCCB commonly used in industry, it was: –
