FAQs
Install the SPC050240S5P in a location with adequate clearance for both front access and maintenance. The device uses external side mounting and a NEMA 4X enclosure, which protects against dust and moisture. Ensure proper torque on mounting screws, follow conduit entry guidelines, and verify that the panel has a compatible 120/240 V split-phase supply. Always consult the installation sheet and safety standards to avoid overheating or improper cooling.
The protector is designed specifically for 120/240 V split-phase configurations, offering a 50 kA surge rating to handle typical utility and load transients common in commercial settings. Its NEMA 4X enclosure supports durability in varied environments, while the alarm relay provides immediate fault signaling to maintenance systems, reducing the risk of undetected surges affecting critical loads.
The SPC050240S5P is UL 1449 listed for surge protection devices, ensuring compliance with essential safety and performance criteria. It uses a rugged NEMA 4X enclosure suitable for indoor and outdoor applications, supporting reliability in challenging environments and contributing to overall electrical system safety.
The integrated alarm and Form C relay provide real-time status signaling, enabling remote monitoring and automated alerting when surge protection is compromised. This supports proactive maintenance, faster fault isolation, and reduced unplanned downtime by ensuring the protection device communicates its health to building management or SCADA systems.
By preventing transient damage to critical equipment, the SPC050240S5P lowers replacement and downtime costs, extends the service life of panelboards and controllers, and reduces maintenance labor through remote signaling. For facilities with frequent power disturbances, this can translate to measurable uptime improvements and lower total cost of ownership over the protection system’s 10-year warranty.
