SPC
The SPC050240S4P delivers a 50 kA surge rating, providing robust protection against transient events that can damage downstream sensors, drives, and control circuitry. This translates to fewer unplanned outages, lower repair costs, and extended asset life in manufacturing lines and data-driven facilities. In practice, engineers can rely on consistent performance during severe storms or grid disturbances, reducing the risk of nuisance tripping while maintaining production throughput. The 120/240 V split-phase rating makes it compatible with common industrial and commercial power architectures, enabling seamless integration into existing panels without costly reconfigurations. The NEMA 4X enclosure supports indoor and outdoor installations, ensuring reliable protection in damp or dusty environments and simplifying compliance in outdoor equipment rooms. The Form C relay provides a simple signaling interface for remote fault indication or interlock logic, enabling coordinated protection within automated systems. External side mounting streamlines installation, reduces mounting depth, and minimizes footprint, which is especially valuable in retrofits or fan-out panel configurations. A 10-year warranty reinforces long-term value and reduces lifecycle maintenance concerns, while UL 1449 certification confirms adherence to recognized safety and performance standards. This combination of protection, durability, and ease of installation makes the SPC050240S4P a practical choice for control panels, machine enclosures, outdoor substations, and other critical loads that demand reliable surge suppression. The SPC series is designed to work as part of a cohesive protection strategy, helping facilities meet uptime targets and regulatory expectations in demanding environments.

FAQs
SPC050240S4P is designed for industrial control panels, outdoor electrical cabinets, and commercial facilities that rely on 120/240 V split-phase systems. It provides a robust 50 kA surge protection to shield sensitive drives, relays, and sensors from transient events. It integrates with SPC-series devices to deliver coordinated, site-wide protection and to simplify procurement and maintenance planning.
Yes, SPC050240S4P is UL 1449 listed, confirming adherence to recognized safety and performance standards for surge protection devices. This certification supports regulatory compliance in facilities such as data centers, manufacturing floors, and commercial buildings, and helps with code compliance during inspections. Always verify the current certificate to ensure alignment with your project requirements.
The SPC050240S4P uses external side mounting, designed for straightforward integration into standard electrical panels and enclosures. Its compact footprint (5.5 in depth, 6 in height, 3.19 in width) and 2.5 lb weight facilitate retrofits and space-constrained installations. Wiring is streamlined with a simple, durable connection approach that supports quick commissioning and reduced labor time.
Yes. The device is rated for 120/240 V split-phase systems and housed in a NEMA 4X enclosure, making it suitable for outdoor or damp environments. This enables protection for outdoor equipment racks, exposed subpanels, and weather-prone installations while maintaining safe performance and regulatory compliance.
SPC050240S4P carries a 10-year warranty, reflecting Eaton’s confidence in long-term reliability. This reduces total cost of ownership by lowering replacement frequency and maintenance interruptions. For best results, incorporate periodic inspection and testing into your preventive maintenance plan to ensure ongoing protection and to quickly detect any performance drift before a surge event occurs.
