Feature → Business Impact → Application: High-energy surge protection rating of 100 kA per phase and 200 kAIC short-circuit rating minimizes the risk of equipment damage during transient events, reducing unplanned downtime and extending the life of critical assets in 480Y/277V panelboards. This supports reliable manufacturing operations and helps meet industry reliability targets while maintaining compliance with electrical standards. Feature → Business Impact → Application: EMI/RFI filtering delivering up to 50 dB of noise attenuation from 10 kHz to 100 MHz lowers electrical noise impacting drives, PLCs, and sensors, improving process stability and product quality on assembly lines and in automated facilities. Feature → Business Impact → Application: Audible alarm with silence button, Form C relay contact, and a surge counter with rest button provide real-time status and remote signaling for maintenance teams, enabling proactive maintenance and faster fault isolation in control rooms and switchgear areas. Feature → Business Impact → Application: Bottom terminals and internal integrated mounting simplify installation, reduce on-site labor, and improve wiring reliability when integrating into panelboards (PRL-C), leading to faster project completion and consistent electrical workmanship. Feature → Business Impact → Application: 4W+G capability and a compact footprint support compliant grounding schemes and space-efficient installations in crowded electrical rooms, with compatibility across standard enclosures and retrofit scenarios for existing infrastructure. This combination of protections, signaling options, and ease of installation translates into measurable improvements in uptime, compliance, and total cost of ownership for industrial facilities and OEM projects.

FAQs
SPD100480Y2D is designed for straightforward panelboard integration. Use bottom-terminal wiring for secure terminations and follow internal mounting guidelines to minimize wiring length and impedance. Its 277/480V rating suits typical commercial and industrial distribution panels, and compatibility with PRL-C panels helps streamline retrofit projects and new installs alike, reducing field wiring complexity and downtime during deployment.
This device provides up to 100 kA per phase surge capability and a 200 kA short-circuit rating, with a 20 kA nominal discharge current. These specifications deliver robust protection for critical loads, minimizing the likelihood of equipment damage during transient events and providing a clear margin for typical industrial surge conditions.
Yes. The unit carries UL 1449, UL 1283, and UL Listed certifications, signaling adherence to established surge protection and electrical safety standards. In addition, EMI/RFI filtering contributes up to 50 dB of noise attenuation from 10 kHz to 100 MHz, supporting cleaner control signals and improved equipment performance in noise-sensitive environments.
SPD100480Y2D includes a surge counter with a rest button for monitoring event history, along with an audible alarm (silence option) and a Form C relay contact for remote signaling. These features enable proactive maintenance planning, quick fault identification, and easy integration with building or plant monitoring systems.
Installing SPD100480Y2D reduces unplanned downtime by limiting transient overvoltages that could trip breakers or damage drives and controllers. Its robust 277/480V protection, noise filtering, and signaling capabilities help meet regulatory requirements, improve uptime, and lower total cost of ownership through fewer outages and simpler maintenance workflows.
