High surge capacity is the cornerstone of the SPM300240H1X design, delivering up to 300 kA per phase to clamp damaging transients before they reach sensitive equipment. The business impact is clear: fewer unplanned outages, reduced maintenance costs, and longer life for motors, drives, and sensors across your line. This is especially valuable in 240V delta/high-leg configurations used in manufacturing floors and processing plants. Compatibility with 240 delta (4W+G) systems ensures correct protection without mis-wiring or nuisance tripping. In practice, engineers can specify this SPD with confidence in 4W+G networks where a dedicated grounding path is required, minimizing the risk of ground faults and ensuring safer shutdown when transients occur. Rugged installation is supported by a NEMA 4X enclosure with an internal terminal block, enabling reliable indoor or outdoor mounting in harsh environments. The internal terminal block reduces wiring errors and accelerates panel assembly, while the enclosure resists corrosion, moisture, and dust in factory floors and outdoor substations. Operational monitoring is straightforward thanks to the standard surge counter, which records events for trending and preventive maintenance. Paired with a durable Max series design, this SPD offers straightforward replacement and serviceability, helping control-room staff verify protection performance during audits or after a surge event. Compatibility with standard panel mounting rails and field connections eases retrofit projects. Compliance and safety are built in: RoHS compliant, UL 1449 and CSA certifications, and a 15-year warranty (20 years if registered) provide confidence for procurement and long-term budgeting. From an ROI perspective, deploying this protected device reduces downtime, extends the life of breakers and drives, and simplifies warranty and maintenance planning. The combination of high-energy handling, durable enclosure, and traceable surge data supports uptime in continuous production environments. It is designed for easy field installation with an internal terminal block and corrosion-resistant enclosure, making it suitable for indoor and outdoor installations in challenging environments.

FAQs
Installers should plan for a proper panel location with cable routing to the internal terminal block, ensure grounding is compliant with a dedicated 4W+G path, and mount the unit on a stable surface compatible with the 50 lb weight. Use the NEMA 4X enclosure in indoor and outdoor environments, and follow UL/CSA installation instructions to avoid nuisance tripping and ensure long-term reliability.
Key specs include 240 delta voltage rating (4W+G), 300 kA per phase surge capability, UL 1449 and CSA certifications, RoHS compliance, a standard surge counter, and a 9.3 in depth, 17.5 in height, 14.91 in width footprint. This combination provides robust transient protection for industrial equipment and drives.
Yes. The device is RoHS compliant and carries UL 1449 and CSA certifications (including CSA electrical notice and edition details). These certifications confirm safety, performance, and environmental compliance for industrial control panels and manufacturing environments.
The built-in surge counter logs transients, enabling trend analysis, maintenance planning, and audit readiness. This data helps determine replacement timing, verify protection performance after events, and supports warranty claims. With a 15-year warranty (20 years with registration), it strengthens total cost of ownership and service strategy.
The NEMA 4X enclosure protects against moisture, dust, and corrosion in indoor and outdoor industrial settings. It is suitable for manufacturing plants, data centers with 240V delta high-leg networks, and utility infrastructure where reliable surge protection and installation ease are critical.
