With a 100 kA per phase surge current rating, SPD100480Y1A delivers substantial energy absorption during transient events. This capability limits equipment damage, reduces unplanned downtime, and extends the life of connected drives, sensors, and PLCs in demanding industrial environments. The device is designed for 480Y/277V systems and is optimized for direct bus mounted panel boards used across manufacturing lines. Operating voltage paths include 320 L-N, 320 L-G, 320 N-G, and 640 L-L, delivering comprehensive line-to-line and line-to-ground protection. This wide coverage supports 4W+G configurations, minimizes wiring complexity, and lowers installation risk. The compact internal mounting simplifies retrofit projects and enables cleaner panel layouts, while direct bus mounting reduces cabling costs and installation time on new builds. Observability features include an audible alarm with a silence button, a Form C relay contact, and a surge counter with a rest button. These capabilities provide immediate fault visibility and easy integration with plant control systems, which translates to faster response and reduced Mean Time to Repair. The device supports routine health checks during maintenance windows without disrupting critical processes. EMI/RFI filtering delivers up to 50 dB of attenuation from 10 kHz to 100 MHz, improving supply cleanliness for sensitive automation networks. This reduces nuisance trips, enhances comms between PLCs and digital I/O, and helps meet EMI compliance in tight factory environments. The surge protection remains active across 50/60 Hz operation, ensuring consistent performance in global facilities. Installation efficiency is boosted by internal integrated mounting and compatibility with Direct bus mounted panel boards PRL1a, 2a, 3a, 3e. A basic feature package keeps setup straightforward for standard configurations, while the 15-year warranty and operating range of -40 to 50 °C support long service life in harsh environments. Certifications including UL 1449 Listed reinforce reliability and safety.
