Circuits in industrial equipment need protection from overcurrents and faults. Though simple in theory, circuit breakers and fuses serve some of the most complex roles in modern electrical systems. Unlike other devices, circuit breakers serve as both operation and protection devices, while fuses are the most reliable method of system protection available.

The Fuses and Circuit Breakers training course explains the design and function of commonly used fuses and circuit breakers. It also discusses how to protect them. This online training course explains fuse and circuit breaker construction, application, testing, and troubleshooting. It includes:

• Fuse uses
• Fuse replacement
• Circuit breaker operation
• Circuit breaker types

Fuses and Circuit Breakers is part of the Plant Electrical Systems training series.
