Product Description

 

Summary

BT BCM 25 RM/4P is for installation at LPZ 0A-1 or higher, protecting low voltage equipment from surge damage. Applied in modular SPD Class I (Class B) for TT or TN-S (4+0 circuit)  power supply system. Designed according to IEC 61643-11/EN 64643-11.

Hightlight Features

  10/350μs, 8/20μs sparkgap, Three-phase lightning surge arrester.

  Lightning impulse current withstand max.25kA (10/350μs).

  Adopt hermetical GDT technology, high follow current extinguishing capacity.

  Extremely low voltage protection level.

  Double thermals for parallel or series (V-shape) connection.

  Multifunctional connection for conductors and busbars.

  Green light indicates functional mode (L-N module).
