Description
Eaton SD32X DIN Rail Mount Surge Protection Device
Product Overview

The SD32X is a high-performance signal and data line surge protection device (SPD) from Eaton's MTL SD series (Crouse-Hinds series), specifically engineered to safeguard sensitive electronic equipment, PLCs, DCS systems, and field instrumentation from damaging voltage transients and lightning-induced surges on signal and I/O cabling.

With a nominal voltage rating of 32V DC / 22V AC and a compact ultra-slim design, the SD32X is the ideal solution for protecting 4-20mA loops, digital outputs, alarms, LEDs, solenoid valves, and other process control applications requiring reliable signal integrity.

Model Number Decoding: SD32X
Code Segment Meaning
SD Surge Protection Device (SPD) — MTL SD series
32 Nominal voltage rating — 32V DC / 22V AC
X Denotes the low-resistance variant with 400mA nominal current, optimized for higher bandwidth applications
Key Features & Benefits
  • 20kA Maximum Surge Current: Robust protection against lightning strikes and power grid switching transients
  • Optimized for 4-20mA Loops: Specifically engineered for process I/O applications with negligible signal degradation
  • Ultra-Slim DIN Rail Mounting: Compact 7mm width for standard 35mm DIN rail installation
  • Low Series Resistance: Designed for higher bandwidth applications — minimizes signal interference
  • ATEX Certified: Intrinsically safe for Zone 2 hazardous areas
  • Fast Response Time: Responds to overvoltage events in less than 1 nanosecond
  • Auto-Resetting: Self-resets after each surge event — no manual intervention required
  • 10-Year Product Warranty: Backed by Eaton MTL's industry-leading "No Fuss" warranty
