High-energy surge capability defines the core protection: 50 kA surge rating provides robust defense against high-energy transients, reducing the likelihood that spikes reach downstream devices. This protection lowers PLC faults, drive trips, and unplanned downtime, improving line reliability for machine control panels and servo-driven equipment across automotive, packaging, and general manufacturing environments. Rugged NEMA 4X enclosure delivers weather and washdown resilience, minimizing dust ingress, moisture exposure, and corrosion in harsh facilities such as food processing and chemical plants. The Form C relay enables remote signaling and interlock control, simplifying automation integration and fault isolation in panel boards and signaling circuits. External side mounting enables quick retrofits and straightforward installation, reducing field labor and downtime during plant upgrades. A 10-year warranty paired with UL 1449 certification supports lower maintenance costs and audit-ready safety compliance, while SPC series compatibility ensures cohesive protection across Eaton protection schemes in industrial environments.

FAQs
The SPC050240N4P uses external side mounting, allowing straightforward installation beside existing panels or in tight spaces. Its compact footprint (5.5 in D x 3.19 in W x 6 in H) and standard enclosure enable retrofit with minimal wiring changes. Ensure the panel location provides adequate clearance for service and hot-swappable protection while maintaining the NEMA 4X environment suitability.
A 50 kA rating indicates the device can absorb a high-energy transient before it propagates to downstream loads, reducing the risk of PLC faults, motor drive trips, and processor damage. In practice, this improves uptime for critical equipment and extends the life expectancy of sensitive electronics in manufacturing lines and process controls.
Yes. The unit is housed in a NEMA 4X enclosure, designed for washdown environments and challenging industrial settings. This construction helps protect against dust, water ingress, and corrosion, making it suitable for outdoor or exposure-prone areas within manufacturing facilities.
The SPC050240N4P is UL 1449 listed, offering recognized surge protection safety compliance. It also uses a durable NEMA 4X enclosure to support rugged industrial use. These certifications support reliability, safety, and regulatory alignment for integrated protection schemes in industrial plants.
Using this surge protector can lower maintenance costs by reducing surge-related equipment failures and unplanned downtime. The 10-year warranty further enhances total cost of ownership, while UL 1449 compliance and robust enclosure minimize replacement frequency and support long-term reliability across critical loads.
