Frequently Asked Questions:

Q. What is the difference between MCCBs and fuses?

A. Fuses contain a metal element that melts when there is an excess current due to overload, while MCCBs have an internal switch that breaks the circuit when there is excess current.

Q. How do you reset an MCCB after it has tripped?

A. After a fault condition is cleared, an MCCB can be manually reset by turning it off and then back on. However, it's essential to identify and resolve the underlying issue before resetting the breaker to prevent repeated tripping.

Q. How do you select a right MCCB for my application?

A. Consider the voltage & current rating of the application, the type of load and any special requirements, such as environmental or hazardous location considerations.
