Features Snap action Patented technology The breaking speed of the circuit breaker is accelerated (breaking time within 2ms), and its breaking capacity and current capacity are improved by utilizing gas-flushing principle. There are several different breaking capacities for each model of the Ex9M circuit breaker. Therefore, users may choose the most optimal breaker as per their actual demands. The maximum breaking capacity of each model of Ex9M circuit breaker is up to 150 ka. Prospective peak value Actual peak value Limited let-through current U-Type repulsive electrical circuit, intensifies the repulsion forces and creates a fast-contact opening. Force F2 Energy after current-limiting Prospective short circuit current Upper fixed contact Force F1 Lower fixed contact Gas-Flushing Principle When the circuit breaker breaks the short circuit current, large quantities of high-temperature and high-pressure gas will be generated. A special gas flow path is designed for the Ex9M breaker, which will lead gas being generated to the fast-actuating mechanism. The auxiliary mechanism is activated by the gas pressure, and the entire breaking time may be controlled within 2 ms. Consequently, the damages caused by the short circuit current to the electric components and the busbar are greatly decreased. Current-limiting capacity Current limiting means the limiting increase of the short circuit current in a circuit. In a circuit protected by the Ex9M product series, both the peak value and energy I 2 t of the short circuit current generated are far less than expected. U-Type fixed contact design The pre-breaking technique may be realised by means of a unique U-Type fixed contact. The pre-breaking technique refers to that of the electrodynamic force generated through the U-Type fixed contact and that which occurs on moving contact are mutually repulsed when the short circuit current flows through acontact system. The higher the short circuit current, the bigger the repulsive electrodynamic forces they generate simultaneously. Prior to releasing, the electrodynamic repulsive forces may separate the moving contact from the fixed contact, and the equivalent resistance between these two contacts is increased by stretching the electrical arc. AX AL Double break design The current-limiting function of the pre-breaking technique is enhanced because of an increase in instantaneous arc resistance and arc voltage and a fast drop in the current increase rate. Reduces the damage and loss of equipment and the power lines caused by a short circuit current, improves the safety, and cuts down on the cost of a secondary protection device. AX Modularized design Circuit breakers: For circuit breakers within the same frame, without reference to the size of the breaking capacity and rated current, the dimension is the same. Accessories: Users may select accessories as per their demands and expand the functions of the circuit breakers. 03

Distribution of magnetic field between contacts The Ex9M 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: L N e e e e i i Arc is pushed into the arc-quenching chamber due to the magnet effect. Moving contact Fixed contact Magnetic-blow quenching principle Ensuring that a strong electrodynamic repulsion force will be generated as soon as a short-circuit occurs. Ensuring that the electrical arc can be blown into the arcing chamber instantly. Ensuring that there will be sufficient pressure 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. 04
