Description
TDSMT277
Transient Discriminating MOVTEC, 230-277 V Un, 80 kA 8/20 μs Nominal Discharge Current (In), Per Mode
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. They are ideal for point-of-entry shunt protection applications where robustness and high surge ratings are required.
The Movtec family is designed to suit many distribution systems including TN-C, TN-S, TN-C-S and TT. They can be selected for use with distribution systems with nominal voltages of 230-277V at frequencies of 50/60 Hz.
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.
