Features and Benefits

Safety

AC Circuit breakers help prevent electrical fires and damage to electrical equipment by interrupting the flow of current in case of a fault.

Convenience

AC Circuit breakers can be easily reset after resolving the issue that caused the trip, unlike fuses that need to be replaced.

Selectivity

AC Circuit breakers can be designed to trip at different current levels, allowing for better coordination and isolation of faulty circuits in a system.

Reliability

AC Modern circuit breakers are designed to operate with high accuracy and minimal maintenance, ensuring the long-term protection of electrical systems.
