INTRODUCE


DVM2,DVM2RT, DVM2L,DVM2E and DVM2El series of circuit breakers are new upgraded circuit breakers researched and developed by the company combined with the advantages of similar international products and demand of domestic and international markets.

With insulation voltage up to 1000V, the circuit breaker is applicable for distribution systems of AC5OHz, rated working voltage 690V and rated working current from 10A to 8O0A,used to distribute electric power energy, protect circuits and power equipment against overload, short-circuit,undervoltage and so on, also can be used for infrequent startup of motor and protect it from overload,short circuit of undervoltage.

It is featured with small size, high breaking, short flashover, etc., is the ideal product for users. it can be vertically installed or horizontally installed.DVM2DC series DC moulded-case circuit breaker (hereinafter referred to as circuit breaker)is suitable for DC systems of rated voltage upto and including DC 1000V and rated current 10~800A, used to distribute electric power energy , protect circuits and power equipment against overload,short circuit and so on.

The products can be fed with wires from top and bottom, and it is polarity-free.lt complies with the standards IEC60947-2,GB14048.2, etc.

PRODUCT FEATURES


Current Limiting capacity

Current-limiting refers to limit of the increase of short-circuit current in the loop, and in the lop protected by DVM2, peak value of the short-circuit current and the I't energy in the circuit will be much smaller than the prospective value.

Unique U-shaped static contact can achieve pre-breaking technology:

The so-called pre-breaking technology refers to when short-circuit current flows through the contact system,electric power generated by U-shaped static contact and moving contact is mutual exclusive. The greater the short-circuit currents,the greater the repulsion of the electromotive force, and it s generated together with the short-circuit current at the same time. Before the trip action occurs,the electrodynamic repulsion force can make the static and moving contact separation, by increasing the arcto increase the equivalent resistance between them to achieve the purpose of suppressing increase of short-circuit current.
