Product Description

 

Summary

BT PBM120 275 RM/3+N is for installation at LPZ 0B-1 or higher, protecting low voltage equipment from surge damage. Applied in modular SPD Class I (Class B) for three-phase TT/TN-S (3+1 circuit) power supply system. Designed according to IEC 61643-11/EN 61643-11/GB18802.11.

Hightlight Featrues

  8/20us varistor,  Max. discharge current up to Imax 120kA (L-N module).

  Combined lightning current arrester for three-phase TT/TN-S (3+1 circuit) system.

  Consist of varistors and thermal disconnection devices.  

  Double thermal disconnection device, provide more reliable protection.

  Multifunctional connection for conductors and busbar.

  Green windows will change to red when fault and also provide remote alarm control at the same time.
