FAQs
The SPM300480D1X is designed for 480 Delta (3W+G) configurations with a compact single-module footprint. Installers should plan on routing conductors through the internal terminal block and securing the device in a protected, accessible location. Ensure compatibility with existing panel schedules and confirm enclosure rating meets environmental requirements (NEMA 4X). Typical wiring and clearance follow standard DIN rail or panel mounting practices used in industrial automation.
The unit provides up to 300 kA per phase surge protection. This high rating is designed to clamp transient voltages effectively across three-phase with ground systems, protecting downstream devices such as drives, PLCs, and contactors. In practice, it reduces nuisance tripping and undesirable downtime while preserving uptime for critical loads in harsh industrial environments.
Yes. The SPM300480D1X uses a NEMA 4X enclosure with an internal terminal block, delivering weatherproof and washdown-capable protection ideal for factories, outdoors, or corrosive environments. The rugged construction supports reliable operation under vibration, dust, and moisture exposure typical in manufacturing and process installations.
The device is RoHS compliant and UL listed for 1449 and 1283, with CSA certifications (including CSA Std. C22.2 No. 8-M1986 and CSA Electrical Notice No. 516 Ed 1). These certifications provide regulatory confidence for global procurement, including North American and applicable international projects.
Investing in the SPM300480D1X yields ROI through reduced downtime, lower risk of costly equipment damage, and extended asset life. The unit includes a surge counter for performance tracking, simplifying maintenance scheduling and compliance reporting. The long warranty (15 years, 20 years with registration) further lowers total cost of ownership for capital-intensive manufacturing and data-center projects.
