DAM11 Series Moulded-Case Circuit Breaker
DAM11, DAM11LY, DAM11RT, DAM11E and DAM11EY 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.
DownloadCurrent-limiting refers to limit of the increase of short-circuit current in the loop, and in the loop protected by DAM11, peak value of the short-circuit current and the I2t energy in the circuit will be much smaller than the prospective value.
U-shaped fixed contact
Unique U-shaped fixed 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 fixed contact and moving contact is mutual exclusive. The greater the short-circuit current is, the greater the repulsion of the electromotive force, and it is generated together with the short-circuit current at the same time. Before the trip action occurs, the electrodynamic repulsion force can make the fixed and moving contact separation, by increasing the arc to increase the equivalent resistance between them to achieve the purpose of suppressing increase of short-circuit current.
Feature 1: current limiting capacity
