Using special technology, the EXT series has lower let through voltages at
high surge currents than similar hardwire 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 of the LED indicators.
