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
