Eaton SPC200240S4P Surge Protection Device - UL 1449

The SPC200240S4P offers a 200 kAIC interrupt rating, which translates to robust protection against high-energy surge events, reducing the risk of equipment damage and unplanned downtime in demanding facilities. This capability directly lowers maintenance costs and extends the service life of sensitive drives and controllers, especially in environments with frequent switching transients. Its 120/240 V split-phase rating covers a wide range of industrial loads, enabling reliable protection across MCCs, VFDs, and control panels without the need for custom configurations. The NEMA 4X enclosure ensures ingress protection from dust, water, and corrosion, supporting installation in damp or outdoors-adjacent spaces and simplifying compliance with harsh-environment standards. The Form C relay offers signaling and interlock capabilities, enabling remote status monitoring and integration with automation logic for safer, more efficient operations. External side mounting simplifies retrofits and field upgrades by minimizing enclosure disassembly and allowing quick, secure installation. With UL 1449 certification and a 10-year warranty, engineers can justify protection investments with confidence, knowing both safety and total cost of ownership are addressed. The SPC series is designed to work with standard Eaton control components and is compatible with existing panel wiring practices, reducing training time and accelerating deployment in new builds or upgrades. Real-world industry contexts show that reliable SPD protection can improve line uptime, protect critical variable frequency drives, and support energy-management initiatives by minimizing surge-induced faults.
