The TRS-B100 is a premium, ultra-high-capacity Type 2 Surge Protective Device engineered for the most demanding industrial and commercial AC power systems. Built with advanced MOV technology, it offers a superior 60 kA nominal discharge current and a massive 100 kA maximum discharge capability (8/20µs), positioning it as a top-tier solution for heavy-duty surge mitigation in critical infrastructure.

Designed for 230 V AC applications, the TRS-B100 features an ultra-fast response time of less than 25 ns and a low voltage protection level Up of ≤ 2.0kV, ensuring exceptional protection against severe switching surges and induced lightning overvoltages. The device incorporates a pluggable cartridge for easy, tool-free module replacement and includes a clear visual red status window for immediate fault detection. Its durable construction and DIN-rail compatibility allow for reliable integration into large power distribution panels.
