Hightlight Features

•  Combined module SPD for 3 Phase Wye electrical systems (3W+G).  

•  Max. Discharge current (Imax) up to 50kA 8/20µs.

•  Short-circuit current rating (SCCR) 200kA.

•  Double thermal disconnector device, providing more reliable protection.

•  Green window will change when fault and also provide remote alarm control at the same time.

 

Summary

    BT PUM 3WY 480 RM/3P(815075) Surge protector mainly used in the main distribution system, provide the best protection as they designed to protecting low voltage equipment against indirect surges with ensuring a low protection level (VPR).

     Application in AC voltage system of 3 Phase Wye electrical systems, for example, computer, communication, or control equipment. Designed according to IEC 61643-11 and UL 1449-4th type 4-1 combined SPD Modules.
