Unpacking
1. After unpacking the product, you should carefully read whether the parameter label matches the system (including the rated operating voltage of accessories such as intelligent controllers, undervoltage releases, shunt releases, closed electromagnets, and electric energy storage mechanisms);
2. Shake the circuit breaker to the "test" position, connect the power of the secondary circuit, and check whether the control accessories work normally;
3. After confirming that it is correct, shake the circuit breaker to the "connected" position and put it into operation.
maintain
1. The dust should be cleaned regularly to keep the insulation performance of the circuit breaker good;
2. Regularly check the contact system, especially after each short-circuit current is broken, check whether the arc extinguishing chamber is intact, whether the contacts are in good contact, and whether the connecting parts are loose;
After reaching the mechanical life, you should contact the manufacturer for maintenance.
