Eaton SPD100240D1P Surge Protection Device - UL 1449

External sidemount installation simplifies field integration. By placing the surge protection device on the exterior of the control cabinet, technicians avoid pulling conductors through crowded panels, reducing wiring errors and commissioning time. This layout also minimizes heat build-up inside enclosures and makes future upgrades more manageable, which is especially valuable during line expansions or retrofits in existing facilities. The 100 kAIC interrupt rating translates to real-world protection. In incidents where large surges and fault currents occur, the SPD can shunt harmful energy away from critical loads, reducing the likelihood of motor stalling, drive faults, or PLC damage. For OEMs and maintenance teams, this means fewer field failures and a more predictable production schedule across high-energy processes. A NEMA 4X stainless enclosure stands up to corrosive environments and washdowns. The rugged enclosure protects internal electronics from moisture, dust, and chemical exposure, making it suitable for outdoor substations, manufacturing floors, and harsh industrial settings. This robustness supports longer service intervals and lowers protective-system maintenance costs while maintaining regulatory compliance. Voltage compatibility is ensured with 240V delta operating and 320 L-G, 320 L-L protection, simplifying integration with existing plant feeders and reducing misconfiguration risks during installs. UL 1449 listing and a 15-year warranty provide long-term reliability and regulatory confidence, helping standardize protection across sites and lower total cost of ownership over the device lifecycle. External side mounting and the basic feature package streamline procurement and installation, shortening lead times and improving stock planning for spares and replacements.
