Special features
Basic
High-energy protection: The SPM250480D1X handles up to 250 kA per phase with a 480 Delta (3W+G) configuration, delivering robust surge attenuation for demanding loads. This capability translates into fewer nuisance trips and reduced equipment wear. In practice, motor drives, programmable logic controllers, and sensitive sensors stay within safe voltage bands, supporting continuous production and faster return-to-service after disturbances. Rugged enclosure and simple installation: Housed in a NEMA 4X enclosure with an internal terminal block, the device is designed for harsh industrial environments and straightforward wiring. The single-module format simplifies rack or panel mounting and minimizes cabinet footprint, enabling retrofits or new builds without costly enclosure expansion. Certified performance: UL 1449 and UL 1283 listings, plus CSA Electrical Notices, provide regulatory confidence for data centers, process plants, and machine builders. RoHS compliance ensures materials meet modern sustainability standards, reducing compliance risk across global sites. Long-term value and serviceability: The SPD MAX line offers a 15-year warranty from delivery, extending to 20 years if registered online. This reduces total cost of ownership, and the internal terminal block design simplifies maintenance and future upgrades, preserving protective integrity across asset lifecycles. Compatibility and resilience: With a 480 Delta supply rating and a compact 9.3 by 14.91 by 17.5 inch footprint, this unit fits standard electrical rooms and panels. Its basic protection level is ideal for primary protection schemes where downstream devices are already protected, while providing reliable clamping during transients and ease of replacement if a surge event occurs.
