The TRS7-B100 is a robust Type 1 surge protective device designed to shield electrical installations from direct lightning currents and high-energy impulsive events.
Engineered for buildings equipped with external lightning protection systems (LPS), it forms the first line of defense for main distribution panels, safeguard­ing downstream equipment from severe transient threats.

Its specially optimized spark-gap structure ensures extremely high discharge capability with minimal follow current, delivering stable protection even in demanding industrial or outdoor environments.
With a fast response and low residual voltage, the TRS7-B100 helps maintain operational continuity for sensitive electrical networks exposed to frequent lightning activity.

A clear visual status indicator supports quick on-site inspection, while optional remote alarm outputs allow integration into building monitoring platforms.
Compact, maintenance-friendly, and built for long service life, the TRS7-B100 is a dependable choice for critical infrastructure and commercial facilities requiring primary lightning protection.

Applications

Main distribution boards in buildings with external LPS
Industrial facilities and large commercial installations
Outdoor electrical systems exposed to high lightning density
Sites requiring strong Type 1 surge protection at service entrances
Systems benefiting from visual and remote fault monitoring
