Thermal Magnetic Adjustable MCCB Motor Protective Circuit Breaker
Thermal Magnetic Adjustable MCCB Motor Protective Circuit Breaker
Purple Horn has the Utility Model Patent for the structure of double making & double breaking!
The UKM32 series MCCB are used for making, breaking, and protection of low-voltage distribution systems and motors. Several breaking capacities exist for each model of circuit breaker, meeting
the demands for varying types of protection. Several different rated current levels are available for
each frame size

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.
