FAQs
Begin by verifying system voltage and confirming a 480V delta configuration. Mount the device using its internal integrated mounting method in a suitable enclosure, ensuring clearance for heat dissipation. Connect line-side and load-side conductors per Eaton’s wiring diagram, and wire the Form C relay and audible alarm to the panel’s monitoring network as required. After installation, perform a functional test and confer with your panel schedule to confirm correct integration with the PRL series devices.
80 kA per phase is the maximum surge current the device can safely conduct per phase without sustaining damage. This rating correlates to the energy level typical of industrial transients. For sizing, compare expected surge energy in your location and equipment, and design factors such as service entrance protection and downstream devices. A higher per-phase rating generally indicates greater protection margin for high-energy environments, reducing the risk of upstream component failure.
Yes, the SPD080480D3C is designed for use with switchboards, busways, and panelboards including PRL1a, PRL2a, PRL3a, PRL3e, and PRL4 variants. Its internal mounting and compact footprint simplify integration into existing enclosures, while the built-in surge counter and audible alarm provide proactive protection monitoring. Always verify the exact PRL configuration and follow Eaton’s installation guide for wiring and clearance requirements.
The unit is UL 1449 Listed, indicating compliance with recognized surge protection system safety standards. This certification provides confidence in performance under surge conditions and supports regulatory and insurance requirements for electrical installations. UL 1449 Listing is particularly important for mission-critical applications, ensuring consistent surge mitigation and protection feature performance over the device’s 15-year warranty period.
The SPD080480D3C includes a built-in surge counter with a rest button, enabling real-time monitoring of surge activity and easier preventive maintenance planning. This visibility helps justify ROI by enabling targeted replacements before failures occur, reducing unexpected downtime and extending equipment life. The audible alarm also provides immediate fault notification, supporting fast technician response and lower overall maintenance costs.
