DC Switchgear for Railway - DC Switchgear



ENTEC DC Switchgear for Railway DC Disconnector Switch used for no load switching in DC feeder system.

  • DC Disconnector is used for no load switching in DC feeder system. ET-DS design is compact and optimized in order to apply DC panel and Other applications. In addition, sufficient insulation capacity and electric current capacity increase the product safety. Fast operation time accommodate the user convenience.


High durability and reliability

  • Regular operation time and good electrical mechanical characteristics by using of high quality materials.

Reduction of Closing and Opening time

  • Fast operation by reducing time of opening and closing with adopting relevant Motor Gearbox.

High grade Insulation and Sufficient electric current capacity

  • Sufficient current capacity and high grade insulation to protect users from abnormal condition.

Compact and light weight

  • Size and weight are compact and more optimized in order to provide more convenience in handling.

Various operation method

  • Normally use electrical operation however manual operation of DC Disconnector is accomplished in case of unstable power source or power- off.

Various installation arrangement

  • Free Installation directions to accommodate convenience in construction.

Interlock provision

  • To prevent mis-operation, interlock function are applied with Manual Lock and Position Lock.
