PX3TM 50 Surge Protection Panelboard Extension
The PX3TM offers an externally mounted surge solution that can be physically attached to the top or bottom of any panelboard, providing a reduced profile surge solution. PX3TM suppression filter systems feature a powerful failure-free ISMTM (Integrated Suppression Module). The ISMTM contains individual thermally fused and protected MOVs, surge-rated copper busing, robust filtering and advanced remote communications capabilities.
