FAQs
The SPC160277N8P uses external side mounting, supports single-phase 277 V systems, and is designed to fit standard panel enclosures. It integrates with typical incoming feeds and control circuits, enabling straightforward retrofits in existing cabinets. For technicians, this means minimal disruption during installation, fewer rewiring tasks, and compatibility with common control panels and accessory relays.
The 160 kAIC interrupt rating signifies the device can safely interrupt high-energy surge events without tripping prematurely. This improves protection for downstream equipment, reduces nuisance trips, and enhances overall system reliability. In practice, you gain longer service life for sensitive electronics and motors, especially in environments with frequent transient activity or large switchgear openings.
Yes. The NEMA 4X enclosure provides moisture and corrosion resistance suitable for outdoor installations and harsh factory floors. Its filtering and alarm features support robust protection for control panels, PLC cabinets, and machine interfaces. For outdoor use, pair with proper mounting considerations and provide secure cable ingress protection to maintain performance.
UL 1449 listing confirms the device meets established surge protection safety standards, guiding proper installation practices and safe operation. This certification helps with regulatory compliance, end-user confidence, and warranty validity. The enclosure rating and compatibility with standard electrical panels further support code-compliant deployments in industrial facilities.
Maintenance is typically low due to solid-state surge protection and integrated monitoring via the alarm relay. The 10-year warranty reduces long-term risk and replacement costs. ROI benefits come from reduced downtime, fewer component damages, and easier device forecasting for spare parts, especially in high-energy environments where transient events are common.
