The DC high-speed cutoff base is used for the purpose of interrupting the DC power supply system and interrupting the fault current. It provides variety by supporting 900VDC,1800VDC rated voltage and 4000A,6000A rated current capacity.

It is a highly reliable DC high-speed circuit breaker suitable for high switching frequency,heavy load and harsh environments made with a simple structure through optimal new technology design to quickly protect the tram line from abnormalities in the power system. In addition,it is a product selected as a world-class human product with the ability to cut off all currents including small current cut-off (0~500A).

Main components include DC high speed circuit breaker (HSCB),disconnector,and protection relay. All of them are manufactured and delivered by INTEC ELECTRONICS,thus providing reliability and stability of the system.

responsibility

-Using a simple and highly reliable PMA operation method,HSCB guarantees more than 40,000 operation times and blocks accident current at high speed using its own 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.

-Completely cut off arc residue through a non-metallic separator

-High insulation performance ensures driver safety

convenience

-Easy maintenance and safety due to the HSCB of the withdrawal type blocking part

-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.
