Thomas and Betts' SL3 Surge Protection Devices protect against utility-induced switching surges

Thomas and Betts’ line of Current Technology Select (SL3) Surge Protection Devices (SPDs) offers selenium-enhanced protection from utility-induced switching surges that have become more commonplace with the burgeoning smart grid. Current Technology SL3 SPDs also feature a power quality monitoring system with remote accessibility via ModBus and Ethernet.

Current Technology SL3 SPDs also provide true single- and repetitive-surge test data that fully comply with engineering specifications. Additional features include:

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