Frequently Asked Questions

Q1 What is a Molded Case Circuit Breaker (MCCB)?

A Molded Case Circuit Breaker (MCCB) is an electrical protection device designed to protect electrical circuits from excess current caused by overload or short circuits. It features a molded plastic frame housing all components.

Q2 What is the main difference between MCB and MCCB?

MCBs are typically used for low current requirements (up to 100A) in residential applications, while MCCBs handle higher current ratings (up to 2500A or more) and offer adjustable trip settings for commercial and industrial use.

Q3 How do I choose the correct ampere rating (63A, 125A, 400A, 630A)?

The correct rating depends on the maximum continuous current load of your electrical system, wire gauge capacity, and short-circuit protection requirements. Always consult an electrical engineer for proper sizing.

Q4 What environmental conditions are suitable for OFM1 series circuit breakers?

OFM1 series circuit breakers are built for robust performance across standard industrial temperatures, enclosed distributions panels, and protection against overcurrent in diverse operational environments.

Q5 Are these circuit breakers suitable for industrial main distribution panels?

Yes, models such as the 400A and 630A molded case circuit breakers are engineered specifically to serve as main power distribution protection units in commercial and heavy industrial facilities.
