The EXT100M Series is a compact, state of the art high energy surge protection system. Its compact size saves valuable electrical room space. Plus, it can be installed in most retrofit situations. Available with surge rating of 100kA, the EXT100M is listed to Ul 1449 Edition 2.5 and UL 1449 Edition 4. The EXT100M is listed as a TYPE 1 device which means you don’t have to worry about where to install it. It can be installed upstream or downstream of the service main disconnect. The EXT100M series is Modular and “Hot Swappable” – the surge modules can be field replaced without removing the suppressor!

Using special technology, the EXT series has lower let through voltages at high surge currents than standard similar devices. In addition, its technology prevents premature failure under unusual voltage conditions. Exclusive multipath protection means that redundant surge elements continue to provide protection even should an internal surge element fail. The EXT series includes intelligent indicators for each protection mode. You can confirm total protection with a quick inspection. The 100kA EXT100M series units include dry contacts for optional remote monitoring.
