BL LC 24/4M is installed at LPZ OA-2 or higher, or directly at the upstream near the protected devices. Provid protection for four single lines sharing a common reference potential as well as unbalanced interfaces with measuring and controlling system. Designed according to IEC 61643-11/EN 61643-11.
• Composed by two parts: the base and the protection module
• High discharge capacity, low voltage protection level.
• The signal will not be disconnected when replacing the module.
• Minimum space requirements, two pairs line over a width of 12mm (2/3 modules)
BL LC 24/4M is mainly used in lightning protection for measuring and controlling system for Din rail mounted, such as the field bus systems, emergency alarm systems, or telecommunication system.
