MTL SD32X Surge Protection Device 32V 20kA SPD for 4-20mA Loops MTL SD Series
Product Overview

The MTL SD32X is a high-performance surge protective device (SPD) from the trusted MTL SD Series, designed specifically to protect sensitive electronic equipment and systems from damaging transient overvoltage on signal and I/O cabling. Combining ultra-slim space-saving design with proven hybrid protection circuitry, the SD32X delivers 20kA maximum surge current capacity in a compact 7mm wide package suitable for DIN rail mounting.

Key Features
  • Ultra-slim Design - 7mm width enables high packing density on 35mm DIN rail, saving valuable cabinet space
  • High Surge Current Rating - 20kA (8/20µs) maximum discharge current with 3kA nominal rating
  • Multistage Hybrid Protection - Reliable hybrid circuitry provides protection line-to-line and line-to-ground
  • Wide Operating Temperature - -40°C to +80°C, suitable for harsh industrial environments
  • Broadband Compatibility - 25kHz bandwidth supports higher bandwidth applications
  • Fast Response - <1ns response time for instantaneous protection
