The TRS5-B+C is a modular Type 1+2 surge protective device designed for applications requiring easy maintenance and fast module replacement.
Built with high-quality MOV components, the pluggable design enables technicians to replace protective cartridges without disconnecting wiring, reducing downtime and simplifying long-term system upkeep.
With a 7 kA (10/350 μs) impulse rating for lightning current and 50 kA maximum discharge capability, the TRS5 series offers dependable protection for residential and commercial power systems.
Its ≤1.3 kV voltage protection level efficiently limits transient overvoltages to safeguard sensitive downstream loads.
The device includes a clear red fault indicator and supports potential-free remote signaling, enhancing system visibility. Compact and easy to install on a 35 mm DIN rail, the TRS5-B+C is suitable for multi-unit buildings, commercial distribution panels, and installations with routine service requirements.
Applications
Residential and commercial sub-distribution boards
Buildings without external LPS or with moderate lightning exposure
Installations prioritizing quick replacement through pluggable cartridges
Electrical systems requiring simplified maintenance
Distribution panels for offices, retail locations, and small industrial units
