Surge current
80 kA per phase
High surge rating with 80 kA per phase provides robust defense for critical loads, reducing the risk of equipment damage and unplanned downtime. The business impact is clear: longer equipment life, fewer replacement parts, and more consistent production throughput in demanding environments. The application is ideal for manufacturing lines, control panels, and service entrances where transient events are common and uptime is a competitive differentiator. 120/240V split-phase compatibility ensures the SPD integrates seamlessly with common industrial power architectures, simplifying installation and reducing engineering changes. This translates to faster deployment, fewer wiring errors, and smoother panel upgrades across facilities. UL 1449 listing confirms safety and performance standards are met, supporting compliance initiatives and third-party audits while lowering risk. In addition, Power Xpert SPD compatibility enables centralized monitoring and easier asset management, aligning with modern plant automation strategies. The compact NEMA 1 enclosure supports indoor, dry-location installations, enabling straightforward retrofits in existing electrical rooms. Dimensions and weight facilitate mounting in constrained spaces without sacrificing protection, delivering consistent protection with minimal footprint.

FAQs
SPD080240S4K is designed for indoor dry locations inside a NEMA 1 enclosure. Plan for mount in a standard electrical panel, provide proper clearance for air flow, and verify panel knockouts align with the device terminals. Use the included Power Xpert SPD accessories where applicable, and ensure torque values follow the enclosure manufacturer's guidelines to maintain protection integrity.
An 80 kA per phase rating indicates the SPD can safely absorb extremely large transient currents on each live conductor without degrading protection performance. In practical terms, this reduces the chance of transformer or controller damage during utility switching, motor starting surges, or lightning-induced transients, helping to shield critical loads and maintain production continuity.
Yes. The product is specified as part of the Power Xpert SPD family, enabling integration with monitoring and management ecosystems. This compatibility supports remote health checks, event logging, and easier asset management across multiple protection devices, contributing to proactive maintenance and reduced unplanned downtime.
The SPD080240S4K is UL 1449 listed, confirming compliance with established surge protection safety and performance criteria. This certification supports regulatory adherence, supplier qualification, and third-party audits in industrial facilities, enhancing procurement confidence and system reliability.
The device occupies a compact footprint with dimensions of 3.48 in (depth) x 12.05 in (height) x 7.47 in (width) and weighs 6.8 lb, making it suitable for retrofit projects in existing panels or compact new installations. Ensure mounting locations provide adequate clearance, standard conduit or terminal access, and alignment with panel bus routing to minimize installation time and protect signal integrity.
