TYM2 series moulded case circuit breaker main technical performance has reached the advanced level of ninety time international, which has the advantages of compact structure, small volume, high short circuit breaking capacity, without arcing, internal accessory device installed, use the terminal protective cover, adjustable tripping device enhance safety, as well as " base ", " cover " using different color, enhance the aesthetic characteristics.

The series circuit breaker dynamic, static contact and a contact rod ( connection plate flat line ), make full use of short circuit current does not reach the maximum value before the electric repulsion to make dynamic, static contact by repulsion, limitation of arc current density. In addition, the static contact arranged on the periphery in arc burning releases aromatic insulating material, absorbing the arc energy, cooling arc, the arc column shrink and weaken arc spray backward technical measures. At the same time, the use of a arc gas deionization of the arc extinguishing device, which is reduced to zero. The new measures of the application, greatly improves the circuit breaker short-circuit breaking capacity, reduce the equipment volume.

Since the auxiliary device modular insert installation and provide terminal protective cover, as well as adjustable tripping device, ensures that the circuit breaker is used when the safety and reliability of.

TYM2 series moulded case circuit breaker ( hereinafter referred to as the circuit breaker ), apply to the exchange of 50Hz ( or 60Hz ), rated voltage 690V, rated voltage 660V and below, DC and below 250V, rated current 12.5-800A circuits, for the distribution of power, under normal conditions of frequent closing and opening by, and in the lines and equipment overload, short circuit and under voltage protection.

Rated frame size current in 400A and below the circuit breaker, can also be used for cage motor is not frequent starting, running and motor overload, short circuit interruption in and under voltage protection.

Circuit breaker according to the rating limit breaking ability is divided into type S ( standard), M ( of high breaking type), H ( high breaking type).

With isolation function of their corresponding isolated symbols for " degrees "

Installation: installed vertically ( vertical or horizontal installation. ) ( horizontal ).

Circuit breaker with standard: IEC60947-2, GB14048.2
