www.furse.comESP D & TN Series
TSC-0912 - 09.10.12
Technical specification
Derivatives of these protectors are available ready-boxed to IP66, for use in damp or dirty environments. Slim Line (ESP SL), ATEX (ESP SLX)
and PCB mount (ESP PCB) versions are also available. If your system requires a protector with a very low resistance or higher current, see the
ESP E & H Series. Also use the ESP E Series for systems needing a higher bandwidth. Protectors for 3-wire (ESP SL/3W) and RTD (ESP RTD,
ESP SL RTD) are available, as are the space saving protectors (ESP Q, ESP SL Series). The ESP KT and TN Series are additional protectors
specifically for telephone lines. The ESP KS Series are protectors for data and signal lines on an LSA-PLUS module.
