Advanced Magnetic Field Analysis:
For a circuit breaker, the distrbution of the magnetic field in its contact system has a direct impact on its performance, but the magnetic field is not visible. The UKM32 is designed by combining the overall
simulation technique with several tests, which enables a rational distribution of the magnetic
field and endows a circuit breaker with excellent performance capabilities:
1. Ensuring that a strong electrodynamic repulsion force will be generated as soon as a short-circuit
occurs;
2. Ensuring that the electrical arc can be blown into the arcing chamber instantly;
3. Ensuring that there will be sufficient pressures between the moving contact and the fixed one
when the circuit breaker functions normally and the contact resistance between the two contacts
is sufficiently low.
