Hightlight Features
• 8/20us varistor, Max.discharge current up to Imax 100kA (L-N module)/120kA (N-PE 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.
Summary
BT PBM100 385 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.
