80 kA per phase transient protection clamps surges across L-N, L-G, and L-L paths, safeguarding downstream equipment and processes. It supports 320 V L-N, 320 V L-G, 320 V N-G, and 640 V L-L operation across 4W+G configurations, enabling broad compatibility with modern commercial power systems. This delivers longer equipment life, reduces unplanned downtime, and protects critical processes in demanding environments. Designed for direct bus mounted panels PRL1a, 2a, 3a, and 3e, SPD080480Y2A simplifies installation by aligning with Eaton footprints. Internal mounting minimizes external hardware, reduces field wiring errors, and accelerates commissioning in tight spaces. Field trials show faster upgrades and reliable performance, even in harsh environments and temperature extremes. An audible alarm with silence mode provides immediate fault visibility without interrupting operation, while a Form C relay enables simple external signaling or interlocks to integrate with building management. EMI/RFI filtering delivers up to 50 dB attenuation from 10 kHz to 100 MHz, supporting sensitive control networks. These features reduce downtime, shorten troubleshooting cycles, and improve operator confidence. With a 200 kA short-circuit rating and 20 kA nominal discharge, it protects critical loads against severe transients. It operates at 50/60 Hz on 277/480 V wye systems, compatible with most commercial mains. Compact dimensions—9.5 in length, 5.4 in width, 3.45 in height—and a 3.5 lb weight simplify mounting in constrained spaces. Operating range is -40 to 50 C, ensuring stable performance across diverse plant environments and climates. UL 1449 compliance and UL Listed status verify consistent safety, reliability, and performance under load. A 15-year warranty further reduces lifecycle risk and total cost, delivering predictable procurement. The standard feature package includes essential protections and ready-to-install documentation for quick deployment. Engineers gain reliable protection against EMI/RFI disturbances and a durable solution with long-term operational integrity. Overall, this SPD is a future-ready option for direct-bus panel protection with straightforward procurement.
