Description
MTL SD32T3 Surge Protector 32V DC 400mA 3-Wire DIN Rail SPD
Product Overview

The MTL SD32T3 is a high-performance three-terminal surge protection device (SPD) from Eaton's Crouse-Hinds MTL SD Series, specifically engineered for 3-wire transmitters and sensors requiring separate power supply and signal lines. This ultra-slim DIN rail mount module provides comprehensive hybrid surge protection for all three wires simultaneously, making it the ideal solution for protecting sensitive instrumentation in hazardous and harsh industrial environments.

This is the most compact 3-wire surge protector on the market.

Key Features
  • Complete 3-Wire Protection in a Single Unit - Full hybrid surge protection for all three wires in one ultra-compact module
  • Ultra-Slim Space-Saving Design - Exceptionally slim footprint for high packing densities on DIN rails
  • Proven Hybrid Protection Circuitry - Advanced multistage hybrid technology with 20kA maximum surge current
  • No Loop Resistance Added for Signal Lines - Minimal series resistance (2.2Ω per line) with no significant effect on signal accuracy
  • Hazardous Area Certified - ATEX and IECEx certified for potentially explosive atmospheres
  • Simple DIN Rail Installation - Snap-on mounting to standard 35mm top-hat DIN rail
  • 10-Year Product Warranty - Industry-leading long-term reliability assurance

Applications

The MTL SD32T3 is specifically designed for protecting three-wire transmitters and sensors in various industrial applications:

Application Area Specific Use Cases
Process Control 3-wire pressure transmitters, level transmitters, flow meters
Vibration Monitoring 3-wire vibration sensors on rotating machinery
Temperature Measurement 3-wire temperature transmitters
Separately Powered 4-20mA Loops 3-wire 4-20mA transmitters with separate power supply
Hazardous Areas Oil & gas, chemical, pharmaceutical, mining facilities
Safety Systems Emergency shutdown (ESD) systems, fire and gas detectors
Installation Guidelines

Mounting Instructions:

  • Snap the SD32T3 onto standard 35mm top-hat DIN rail until it clicks securely into place
  • Ensure proper grounding through the DIN rail (automatic when mounted on grounded rail)
  • The ultra-slim footprint allows high-density side-by-side mounting

Wiring Instructions:

  • Terminal 1: Power supply positive (+) from field side
  • Terminal 2: Power supply negative/return (-) / common
  • Terminal 3: 4-20mA signal output
Important Notes: The device connects in series with the protected circuit. Series resistance of 2.2Ω is added per line. Ensure all three wires are connected for complete protection. Follow local electrical codes for proper installation.
