High surge capacity translates to real-world protection; with 200 kA per phase, critical equipment sees fewer damaging transients, improving uptime and extending motor and drive life in manufacturing settings. This device’s 480 Delta (3W+G) configuration ensures compatibility with common industrial power architectures, enabling quicker installation and fewer configuration steps. The NEMA 4 enclosure with an internal circuit breaker delivers weather resistance and simplified maintenance, reducing panel space and wiring complexity while keeping fault isolation within reach. UL 1449 listed protection underpins regulatory compliance and buyer confidence, especially for environments subject to strict electrical safety standards. Its compact 9.5 in depth, 15 in width, and 17.05 in height, at 52 lb, balance protection with practical installability in crowded control rooms or outdoor-rated enclosures. The SPD MAX series is designed for Power Xpert SPD workflows, promoting consistent protection across multiple feeders without adding separate protective devices.

FAQs
Install the SPM200480D4R in 480 V delta three‑phase systems following standard panel wiring practices. Ensure proper clearance for the 9.5 inch depth and access to the internal circuit breaker. Use correct terminations for 3W+G connections, observe clearances per UL guidelines, and mount within a NEMA 4 rated enclosure or suitable indoor environment to maximize protection.
SPM200480D4R provides surge protection by absorbing transient energy and clamping excessive voltages before they reach critical loads. With a 200 kA per phase rating, it responds rapidly to surges and works across 480 V delta systems. The UL 1449 listed device reduces equipment wear, minimizes downtime, and supports reliable motor drives and controls.
Yes. The unit's NEMA 4 enclosure is designed for durability in harsh environments, and its internal circuit breaker provides added protection against miswiring and fault conditions. While suitable for indoor or protected outdoor installations when mounted properly, always follow installation guidelines and local codes to ensure reliable operation in challenging conditions.
This SPD is UL 1449 listed, confirming performance under industry safety standards. The device is designed for NEMA 4 enclosures, enabling reliable protection in damp or dusty environments. UL 1449 compliance, combined with a robust enclosure, helps ensure critical electrical protection requirements are met for commercial and industrial facilities.
From a financial perspective, using this SPD reduces total cost of ownership by protecting mission-critical equipment from costly surges and minimizing unplanned downtime. Regular inspection of the enclosure and wiring is straightforward due to its accessible design, while the internal breaker simplifies maintenance and testing. Over time, this translates to faster mean time between failures and a shorter ROI horizon.
