The CRITEC TDS-MOVTEC family of surge diverters offers economical and reliable protection from voltage transients in even the most strenuous applications.The small foot print provides integrators and OEMs with an effective use of real estate when installing within panels and equipment.

Transient Discriminating (TD) Technology, which meets the safety standards of UL1449 Edition 3, provides a superior life by eliminating the common temporary over-voltage failure mode of most SPDs. TD Technology is essential for any site where abnormal over-voltages can occur or where the possible catastrophic failure of traditional technologies can not be tolerated. Alarm contacts are provided which may be used to shut down the system or to activate an external warning if the internal surge material is below optimum condition.

FEATURES

  • Transient Discriminating (TD) Technology provides increased service life
  • Built-in features include TD Technology, thermal protection and short circuit current fusing
  • LED status indication and voltage-free contacts provide remote status monitoring
  • 100 kA 8/20 μs maximum surge rating provides protection suitable for smaller main-distribution panels and an extended operational life
