Summary
BT BCM30 275 RM/1+N is for installation at LPZ 0A-1 or higher, protecting low voltage equipment from surge damage. Applied in SPD Class I+II (Class B+C) for single-phase TT/TN power supply system. Designed according to IEC 61643-11; GB/T18802.11.
Hightlight Features
• Combined lightning current arrester for single-phase TT/TN ( “1+1” circuit) system.
• Single-pole surge protection lightning impulse current to Iimp 30kA (L-N) / 100kA (N-PE).
• Double thermal disconnector devices, providing more reliable protection.
• Multifunctional connection for conductors and busbar.
• Double terminal for parallel or series (V-shape) connection.
• Windows will change to red when fault and also provide remote alarm control at the same time.
