Eaton SPC120240H8P Surge Protection Device - UL 1449

With a 120 kAIC interrupt rating, the SPC120240H8P delivers high-energy transient handling that rapidly dissipates surge energy away from sensitive loads. This reduces insulation stress, minimizes equipment damage, and lowers repair costs after surge events. In practice, it protects motor drives, contactors, and critical control relays in 240V delta feeders, enabling cleaner power delivery and safer plant operation. Configured for 240V delta (4W+G) systems, the SPC120240H8P aligns with common industrial power architectures, simplifying deployment in retrofit projects. By matching the delta grounding scheme, it reduces nuisance tripping and improves surge diversion efficiency across phases. This compatibility translates to faster commissioning and fewer panel rewires during upgrades. Enclosed in a NEMA 4X housing, the device withstands washdowns, dust, and outdoor exposure without compromising performance. The rugged enclosure supports safer installation in harsh environments, including damp or dusty plant floors and outdoor substations. This durability helps facilities meet safety standards and uptime targets without adding protective enclosures. Built-in filtering reduces high-frequency noise that can trigger nuisance trips and misoperation in control circuits. The integrated Alarm and Form C relay enables remote signaling, fault isolation, and condition-based maintenance, improving uptime and maintenance planning. Together with the UL 1449 certification, these features support regulatory compliance and operational confidence during audits. External side mounting simplifies installation in crowded panels by minimizing clearance needs, while its compact footprint (7.5 in L x 8.5 in H x 3.19 in W) fits standard enclosures. At roughly 4 lb, it is easy to handle during retrofit or new-install projects, and the 10-year warranty provides long-term total-cost-of-ownership value.
