Summary
BT PBM120 275 RM/4P 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 TN-S power supply system. Designed according to IEC 61643-11; GB/T18802.11.
Hightlight Features
• 8/20μs varistors for max. discharge current up to 120kA.
• Combined surge arrester for three-phase TT or TN-S ( “4+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.
