The following products are covered by this manual: ISM15_Shell_2(150) ISM15_Shell_2(210) ISM15_Shell_2(275) The model number is shown on the equipment rating plates. If your equipment does not correspond to this number then this manual is not applicable.

  • Page 9: Definitions

    General Figure 1 In comparison to conventional circuit breakers, the Tavrida Electric vacuum circuit breakers comprise of two components: · The ISM (Figure 1) · The CM for controlling the ISM and monitoring both modules (Figure 2) Both modules must only be operated together and are meant for indoor installations only.

  • Page 10: Des Ign And Method Of Operation: Ism And Cm

    Compact design Tavrida Electric develops and produces all vital parts of the circuit breakers themselves. The result of intensive inhouse fundamental and material research are extremely compact vacuum interrupter and magnetic actuators. Optimal selection of all components makes these the most compact and light weight vacuum circuit breaker in the world.
  • Page 11 Closing In the open position the contacts are kept open by the force of the opening springs. To close the contacts the coils of the magnetic actuators are excited by a current impulse of the close capacitors of the CM. As a result the contacts close.

  • Page 24: Interlocking

    Interlocking Interlocking mechanism Interlocking mechanism of the module is based on operation of an interlocking shaft that can be rotated clockwise or counter-clockwise. When the interlocking shaft is rotated clockwise the module becomes acceptable for “close” and “open” operations. Hereinafter this position of the module is called “unlatched”. When the shaft is rotated in reverse direction, i.e.
  • Page 25 Mechanical Interlocking Mechanical interlocking depends on interlocking shaft rotation (refer to figures 28 to 32). The mechanical interface for the connection of mechanical interlocking is placed at the ISM frame between the terminal blocks XT1, XT2 (refer to figure 35). There is a slot on the visible face of the interlocking shaft. If the slot is directed vertically the module is in “unlatched”...

    When designing and mounting a panel for the first time an acceptance of the equipment must be carried out together with Tavrida Electric in order to ensure the installation conditions. The ISM must always be tested and operated together with the CM. Individual testing is not possible and may lead to the destruction of the ISM.

    Fast Transfer Switching Sensitive loads in industrial processes are often configured with a secondary primary feed from the utility for backup and reserve power. For sectors such as oil & gas, slow transfer times from traditional switching solutions result in motor stoppages and lost production time while processes are brought back on-line. The high closing and opening speeds of the ISM15_Shell_2 series allow for a packaged solution.
