UL DIN-rail surge protective devices (SPD) deliver comprehensive UL 1449 Third Edition recognized overvoltage protection. New UL SPDs feature the same great benefits that make choosing, installing and maintaining SPDs a far simpler process. Modular DIN-raildesign with color coding makes it easy to install the right module. Finger-safe construction improves electrical safety, while a rejection feature assures system integrity by preventing misapplication of SPD modules. Vibration and shock resistance according to EN 60068-2 are ideal for harsher conditions present in mining and oil and gas applications.
