As we all know, MCCB generally has three states: ON, TRIP, and OFF. The main function of the trip mechanism is to ensure that the MCCB reliably cuts off the circuit in the event of overload, short circuit, etc.
The machine mentioned in this article is a separate test device specifically used for Trip Mechanism. Its test content includes:
1.ON – TRIP – OFF angle test, force value test
2. Bearing contact force test
3. Trip peak force, distance release test
After the test is completed, the qualified products will be laser marked with a QR code to facilitate subsequent tracking of production progress.
