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.

5. Do you support sourcing discontinued circuit breakers?

Yes, we help source obsolete or hard-to-find circuit breakers and can recommend suitable alternatives.

6. What is your quality assurance policy?

All products come with a 180-day warranty. Customers must provide authorized test reports or visual evidence for any claims within the valid period.
