Usage Instructions
1. The motor protection circuit breaker should be vertically installed, and before installation, please make sure the technical parameters of the product listed on the nameplate can meet your application demands.
2. Before connected to the power system, the electrical switch should be given several times manual operation to make sure it offers reliable, flexible and smooth operations.
3. The electrical circuit is connected if the CLOSING button in black color is pressed. The circuit is disconnected if the OPENING button in red color is pressed.
4. During use, the product should be given monthly check to assure reliable operation.
5. When the motor protection circuit breaker functions to protect the electrical circuit from overload or short circuit damages, users should firstly eliminate the faults in the circuit before resetting the breaker.
6. Product maintenance without authority is not allowed.
7. Before use, please make sure the current adjustment knob is in proper position, so as to avoid using the electrical apparatus in overload conditions.
