Eaton SPC200480N4P Surge Protection Device - UL 1449

200 kAIC interrupt rating delivers high-energy surge handling, protecting downstream devices such as PLCs, servo drives, contactors, and sensors. This translates into fewer unplanned shutdowns, reduced replacement parts, and lower maintenance costs on automated lines situated in harsh environments. By clamping transient voltages quickly, the SPC200480N4P helps maintain accurate process control even during utility disturbances. It is particularly beneficial where nearby welding machines, heavy motor loads, or arc furnaces contribute to transient-rich electrical noise. 488 V single-phase compatibility aligns with common plant power architectures, simplifying integration into existing MCCs and control panels. It supports seamless wiring with the SPC series ecosystem, enabling straightforward expansion and consistent protection across multiple machines without reengineering power distribution. Engineers appreciate the predictable performance and ease of retrofits when upgrading legacy protection schemes. NEMA 4X enclosure delivers weatherproof, corrosion-resistant protection suitable for outdoor installations, washdown zones, and humid factories. The rugged construction reduces enclosure-related failures and simplifies installation in challenging environments, while UL 1449 certification confirms that the device meets industry safety and performance standards. The enclosure design also supports easy cleaning and long-term reliability in demanding applications like water treatment or food processing. Form C relay adds signaling for alarms, remote interlocks, or maintenance indicators, improving visibility to operators and maintenance teams. External side mounting reduces installation time by allowing quick retrofits in existing panels without reworking internal layouts. This combination of signaling and flexible mounting supports proactive maintenance programs and faster fault isolation. Compact footprint and weight—5.5 in length, 6 in height, 3.19 in width, and 2.5 lb—facilitate mounting in tight spaces and compatible enclosures. The 10-year warranty further lowers total cost of ownership by reducing the frequency of replacements and service calls. A ready-to-integrate protection solution for machine builders and panel shops accelerates commissioning while ensuring consistent surge suppression across lines. With specifications published in the SPC series datasheet, engineers can plan protection coverage that aligns with UL 1449 performance requirements and industry best practices for surge suppression. The combination of high surge capacity, robust enclosure, and signaling capability makes it a prudent choice for modern automated facilities seeking reliability and compliance. In practice, this device supports uptime guarantees and helps meet supplier and end-user compliance expectations during audits and inspections.
