The MTL SDM modular range from Eaton’s Crouse-Hinds series takes the established SD range to the next level by introducing a replaceable element. While maintaining unrivalled packing density, the modular design enables easy maintenance by allowing surge protection modules to be replaced without disconnecting the loop wiring.

Key Benefits

• Maintenance Ease: Pluggable modules allow quick removal without disconnecting wiring, significantly reducing replacement costs.

• Slim Design: The 7mm footprint increases packing density, saving cabinet space and reducing overall project costs.

• High Reliability: Delivers a 20kA level of protection, suitable for critical process control environments.

• Uninterrupted Operation: The "make before break" design ensures signal continuity to the DCS during maintenance, avoiding nuisance alarms.

• Visual Diagnostics: Optional LED status indicators provide clear identification of failed modules for immediate rectification.

Technical Specifications & Compliances

• Maximum Surge Current: 20kA

• Voltage Ratings: 7V, 16V, 32V & 55V

• Current Capacity: 700mA & 4A (High Current versions)
