FAQs
The SPM400240D3U is designed for 240 Delta (3W+G) configurations with two modules and a 400 kA per phase rating. Its architectural alignment with the SPD MAX family ensures seamless integration into 240V delta feeder circuits, enabling reliable protection for motors, drives, and panels without changing existing wiring plans.
The internal surge counter increments with each surge event detected by the device, providing a simple, on-site metric for protection activity. Reading the counter typically involves the device’s terminal or a connected monitoring interface per Eaton’s installation documentation, allowing technicians to evaluate event frequency and plan preventive maintenance.
Yes. The device is housed in a NEMA 4 enclosure with an internal terminal breaker, delivering weather resistance and rugged performance suitable for outdoor and harsh indoor environments. This enclosure protects wiring and components from dust, water ingress, and corrosion, reducing the need for additional weatherproofing on most sites.
The SPM400240D3U is UL 1449 and UL 1283 listed and CSA certified, with RoHS compliance. These certifications verify safety, performance under surge conditions, and environmental compliance, reducing regulatory risk, aiding procurement approvals, and supporting warranty eligibility for industrial installations.
The SPD MAX device carries a 15-year warranty from delivery, extended to 20 years when registered on Eaton’s site. This long-term coverage lowers maintenance and replacement costs, improving total cost of ownership by extending protection lifespans and stabilizing budgeting for downstream protection across facilities.
