AOLE series residual currentaction circuit breaker is suitable for use in line AC 50Hz/60Hz, rated current up to 63A. Here's how the AOLE series works. When a person is electrocuted or the leakage current of the grid exceeds the specified value, the circuit breaker with the remaining current can quickly cut off the faulty power supply in a very short time, in order to protect the safety of the person and electrical equipment. It can also be used for overload and short circuit protection of lines, and normally can also be used to infrequently switch on and off electrical equipment and lighting lines.AOLE series is suitable for industrial and commerciallighting distribution systems.
