Electricity plays an important role in the society we live. Almost all the home appliances and the industrial machines work on electricity. Despite its usefulness, electricity can be quite harmful for us when any fault occurs in electrical system. Common faults like short circuit or power overload may result in costly equipment damage. Prevention of such unwanted situations is a must and for these, MCBs and Isolators are integrated in the electrical circuits these days.
Introduction of Miniature Circuit Breaker MCB
It is an automatic tripping switch that is designed by utilizing electromechanical techniques to avoid short circuit or power overload damage. MCB has a solenoid inside and is kept at specific voltage level to keep triggering mechanism in proper balance. Once a problem is assessed in circuit, switch is triggered and then flow of current is discontinued. After resolving the issue in circuit, the MCB can be manually switched on again.
Mostly found in commercial electric system, isolators disconnect circuit from main power supply. The electrical product is used when the system needs to be disconnected from main supply for performing maintenance that involves direct contact with current carrying parts of machinery.
Key Difference Between Miniature Circuit Breaker And Isolator
- MCB is an on-load electrical device that means the circuit breaker works with the energized line whenever a fault occurs. Isolator is purely an OFF-ON manual mains switch which has now been redesigned in miniature size to be compatible with MCB sized Distribution Boards.
