Current Technology® Select® Surge Protection Devices from Thomas & Betts Feature Selenium-Enhanced Protection

Thomas & Betts Power Solutions’ line of Current Technology® Select® (SL3™) Surge Protection Devices (SPDs) now offers selenium-enhanced protection from utility-induced switching surges that have been become more common with the growing smart grid. In addition to the enhanced protection, the SPDs also feature an advanced power quality monitoring system with remote accessibility via ModBus and Ethernet, allowing users to help identify and quantify critical power quality issues at a fraction of the cost compared to standalone power quality monitoring systems.

Current Technology® SL3™ SPDs also provide true single- and repetitive-surge test data that fully comply with engineering specifications, in contrast to calculated values for single- and repetitive-surge data that competitor SPDs provide. Additional features include:

– Underwriters Laboratories (UL) Listed – Type 1 SPDs to UL1449 3rd Edition

– Smaller and lighter footprint – Occupies less space and reduces shipping costs

– Exclusive disconnect barrier – Units with integral disconnect come standard with a safety barrier that blocks access to the line side of the disconnect

– Improved standard base monitoring – Offers tri-colored LEDs that indicate remaining protection, audible alarm, alarm silence and dry relay contacts

Current Technology® SPDs also fulfill the requirements imposed by the recently implemented National Electrical Code® (NEC®) Article 708, Critical Operational Power System (COPS), which requires that SPDs be installed at each voltage level inside of a facility, as well as Underwriters Laboratories’ UL96A requirements for lightning protection systems.
