Eaton SPD080480D1C Surge Protection Device - UL 1449 Listed

80 kA per phase surge current rating provides robust protection for motor drives, control electronics, and sensitive devices, dramatically reducing the risk of damage during voltage transients. The result is fewer outages, lower maintenance costs, and extended service life for critical loads. This device is engineered for 480 V delta systems and supports 640 L-G and 640 L-L MCOV to sustain reliability across frequently switching loads. In practice, it translates to fewer unplanned shutdowns during storms or switching events, protecting both productivity and capital equipment. When paired with proper panel protection strategies, it becomes a core element of a resilient electrical distribution system. Internal integrated mounting simplifies installation by eliminating external brackets and reducing enclosure footprint, enabling quicker deployments in crowded switchgear rooms. The compact footprint—9.5 in length, 5.4 in width, and 3.45 in height—and a modest 3.5 lb weight make retrofit and new installations straightforward in existing assemblies. This design minimizes space conflicts with busways and supports clean routing of conductors, which helps maintain labeling and serviceability. Long-term, the integrated mounting reduces labor time during commissioning and simplifies future maintenance tasks. Audible alarm with silence button and Form C relay contact provide immediate fault notification and remote signaling to a central monitoring system, which improves mean time to repair and reduces response time. EMI/RFI filtering delivers up to 50 dB attenuation from 10 kHz to 100 MHz, helping to meet sensitive control system requirements and minimize interference with nearby instrumentation. The device ships with a basic feature package and supports a surge counter with a rest button for on-page diagnostics. UL 1449 certified and UL Listed, the SPD080480D1C meets rigorous safety criteria and provides documented performance in protecting life-safety and equipment. It also aligns with widely adopted standards such as IBC 2006, CBC 2007, and UBC Zone 4, enabling compliant installation in a broad range of commercial and industrial facilities. A 15-year warranty adds total cost of ownership advantages by reducing replacement risk and post-sale support. Compatibility with Eaton’s basic feature package and the stated usage with switchboards, busways, and panelboards PRL1a, 2a, 3a, 3e, and 4 helps maintain consistent protection architecture across evolving electrical infrastructure. By standardizing on the SPD series within existing protection schemes, engineers can streamline procurement, simplify maintenance planning, and minimize training requirements for maintenance staff.
