Frequently Asked Questions

What is a Molded Case Circuit Breaker (MCCB)?

A Molded Case Circuit Breaker (MCCB) is an electrical protection device designed to safeguard electrical circuits from excessive current, overloads, and short circuits in industrial and commercial environments.

What is the main difference between an MCB and an MCCB?

Miniature Circuit Breakers (MCB) are primarily used for low-current applications (up to 100A) in residential setup, whereas Molded Case Circuit Breakers (MCCB) cover higher current capacities (up to 2500A) with adjustable trip settings.

How do I choose the correct current rating for a circuit breaker?

Selecting the right amperage (such as 63A, 125A, 400A, or 630A) depends on the system's maximum continuous load requirements and the current-carrying capacity of the connected wiring system.

Where are OFM1 series circuit breakers commonly applied?

OFM1 series breakers are typically deployed in electrical power distribution systems, motor protection panels, main switchboards, and heavy industrial machinery controls.

What protection features do these circuit breakers offer?

They feature reliable thermal-magnetic trip mechanisms, high breaking capacity, durable insulation housing, and quick response times against short circuits and continuous overloads.
