Industrial Circuit Breakers & Protection Systems (MCB, MCCB, ACB)

This course provides a practical and industry-focused understanding of industrial circuit breakers and protection systems, designed for maintenance engineers and technicians. It covers the working principles, applications, and selection of MCB, MCCB, and Air Circuit Breakers (ACB) used in low-voltage electrical systems.

Learners will understand overload, short-circuit, and fault protection, along with breaker tripping characteristics and coordination. The course also explains the role of breakers in distribution panels, motor control centers (MCC), and industrial plants.

Special emphasis is given to maintenance practices, including inspection, testing, troubleshooting, and safe isolation procedures (LOTO). Real-world scenarios from industrial environments such as steel plants and commercial buildings are included.

By the end of this course, learners will be able to identify, operate, and maintain circuit breakers safely and efficiently.
