FAQ

1. What is a circuit breaker used for?

A circuit breaker is used to protect electrical circuits from overload and short circuits by automatically interrupting current flow.

2. What is the difference between a fuse and a circuit breaker?

A fuse must be replaced after operation, while a circuit breaker can be reset and reused multiple times.

3. What types of circuit breakers are available?

Common types include thermal, magnetic, and thermal-magnetic circuit breakers, each suited for different protection requirements.

4. How do I choose the right circuit breaker?

Selection depends on current rating, voltage rating, trip characteristics, and application environment.
