With a 50 kA surge current rating at 240V delta (4W+G), the SPC050240H3P delivers strong transient suppression for heavy loads. This protection reduces equipment wear, lowers nuisance trips, and minimizes unplanned downtime on production lines. End users typically place it at feeder or branch protection points to maximize lifespan of critical assets. Built in a NEMA 4X enclosure, the device remains protected against dust, water ingress, and corrosion in challenging environments. This rugged construction simplifies field deployment in outdoor cabinets and damp plant rooms, alleviating the need for additional protective housings and reducing installation costs. The audible alarm provides immediate local visibility of fault events, speeding response and troubleshooting. The product’s compact footprint and external side mounting simplify installation in constrained panels, while dimensions of 5.5 in L x 6 in H x 3.19 in W and a 2.5 lb weight support easy retrofits. UL 1449 listing and a 10-year warranty reinforce regulatory compliance and long-term value, making it a reliable choice for machine builders and end users alike.

FAQs
The SPC050240H3P is designed for 240V delta electrical systems in industrial panels, including motor control centers, drives, and PLC cabinets. It protects critical equipment such as VFDs, contactors, and control logic from transient surges. Its NEMA 4X enclosure makes it suitable for damp, dusty, or outdoor environments, and external side mounting simplifies retrofits in crowded installations.
A 50 kA surge rating per phase allows the SPD to absorb large transient currents without passing damage to downstream devices. This reduces component stress, extends the life of drives and controllers, and lowers maintenance costs. In facilities with heavy motor loads or frequent switching, expect fewer unplanned outages and more stable processes.
Yes. The SPC050240H3P uses external side mounting, simplifying installation in tight panels. It is rated for 240V delta (4W+G) systems, including high-leg delta configurations common in industrial settings. Its compact form factor and mounting method support quick retrofits and clean wire management, reducing labor costs during panel upgrades.
This device is UL 1449 listed, confirming safety and performance for surge protection devices. It also features a NEMA 4X enclosure, offering robust ingress protection against dust and water for indoor and outdoor use. Together, these specifications simplify regulatory audits and support safety programs across industrial environments.
By limiting surge-related damage to motors, drives, and PLCs, the SPC050240H3P reduces unplanned downtime and maintenance costs. The audible alarm enables rapid response, while the 10-year warranty signals long-term reliability. For capital projects, the SPD lowers overall maintenance spend, extends asset life, and contributes to safer, more predictable production operations.
