Surge Protection



Current Technology raises the bar for surge protection by offering the most robust surge protection on the market with leading edge remote monitoring capabilities.

The newly released ISM series of products (SL3, TG3, and PX3) are all listed by UL to UL1449 3rd Edition as Type1 SPDs backed with 3rd party validated testing, providing "true" single surge ratings.

The SL3 series continues to be the only SPD on the market that offers the benefits of longer duration over voltage protection while the new PX3 offers a convenient alternative to "internally" mounted surge protection.

The updated Mastermind monitoring package tracks facility critical power quality information, reporting the type of event, duration and magnitude while allowing remote access via ModBus and/or Ethernet communications.

No other industry manufacturer can match the performance, reliability, or capabilities of Current Technology, the leader in surge protection.
