MTL SD32T3 32V DC 400mA 3-Wire Surge Protector DIN Rail Mount SPD for Vibration Sensors

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.

• 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

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