The TRS5 Dual Series TRS5-B+C is a compact Type 1+2 surge protective device engineered to safeguard low-voltage AC systems against both lightning-generated currents and switching-induced overvoltages.
This dual-module design offers enhanced installation flexibility, supporting both 2-pole and 4-pole configurations, making it suitable for a wide range of distribution systems.
Built with high-performance MOV technology, the TRS5 Dual Series delivers a 12.5 kA (10/350 μs) lightning impulse withstand capability and up to 50 kA (8/20 μs) maximum discharge current. Its ≤1.3 kV protection level ensures surge energy is rapidly diverted while maintaining safe voltage limits for downstream equipment.
A clear red visual indicator provides straightforward status monitoring, while optional potential-free remote signaling contacts allow the device to be integrated with supervisory or building management systems.
The pluggable module structure simplifies routine maintenance and enables quick replacement without altering wiring.
Designed for reliable DIN-rail mounting, this device is an ideal solution for modern distribution infrastructures requiring both high energy handling and service convenience.
Applications
Dual-pole or multi-pole distribution panels requiring flexible surge protection
Residential and light-industrial power networks operating at 230V AC
Buildings with moderate lightning exposure or switching-heavy electrical loads
Sub-distribution boards feeding lighting circuits, small machinery, or office equipment
Systems requiring visual fault signaling and optional remote monitoring
Installations that prioritize fast, tool-free module replacement
