The DC high-speed circuit breaker is a pull-out type main circuit breaker based on DC high-speed cut-off and blocks the interruption and accident current of the DC power supply system. EDB Series is a highly reliable DC high-speed circuit breaker suitable for high switching frequency,heavy loads and harsh environments made with a simple structure through an optimal new technology design to quickly protect the tram line from abnormal phenomena in the power system.

By adopting the Permanent Magnetic Actuator (PMA) function as an operation method,the structure of the HSCB is minimized and many operations can be performed without major maintenance even in an overload environment.

EDB Series is divided into light rail (EDB-09) with DC 900V supply and heavy rail (EDB-09) with DC 1,800.

responsibility

-By applying a simple and highly reliable PMA operation method,it guarantees more than 40,000 operation times and blocks accident current at high speed using the built-in overcurrent trip device.

-Completed type test certification based on IEC standards through internationally recognized organizations (CESI,KERI)

-Acquired KT Mark,recognized for the only DC breaking technology in Korea and product performance of DC high-speed circuit breaker

safety

-Eliminate blind spots of system protection by applying small current blocking technology with its own patent

-It has sufficient current carrying capacity that does not exceed the specified temperature (85 degrees or less) even if the rated current is energized to the self-saturation state.

-High insulation performance ensures driver safety

convenience

-Simple structure allows interface with various types of switchboards and protection relays

-Easy to maintain and repair as it is made in a simple structure through CAD and 3D design.

-Manual/automatic withdrawal is possible
