Product Description

 

Summary

BT PBM120 275 RM/2P 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 single-phase TN power supply system. Designed according to IEC 61643-11; GB/T18802.11.

Highlight Features

  8/20μs varistors for max. discharge current up to 120kA.

  Combined lightning current arrester for single-phase TN ( 2+0 circuit) system.

  High discharge capacity, quick response. 

  Consist of varistors and thermal disconnection devices.  

  Multifunctional connection for conductors and busbar.

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