FAQs
The SPM300240S1X uses a single-module design with an internal terminal block, simplifying wiring and reducing field termination errors. Its 50 lb weight and compact footprint (9.3 in L x 14.91 in W x 17.5 in H) support straightforward retrofits or new panel installations. Properly securing the unit to a suitable chassis and following the EN/UL mounting guidance ensures robust performance in demanding environments.
Rated at 300 kA per phase, the SPD MAX SPM300240S1X absorbs and clamps transient voltages to protect downstream components, including drives, relays, and PLCs. This high-energy capability is critical for safeguarding sensitive equipment in medium-to-large power quality events, reducing arc-flash risks and downtime while maintaining load integrity on 120/240 V systems.
Yes. The unit features a NEMA 4X enclosure with an internal terminal block, designed for indoor and outdoor-rated environments. This rugged construction provides weather and dust resistance, enabling reliable protection in exposed electrical rooms, outdoor panels, and other challenging settings without requiring excessive enclosure upgrades.
The SPM300240S1X is UL 1449 and UL 1283 listed and CSA certified (CSA Std. C22.2 No. 8-M1986; CSA Electrical Notice No. 516 Edition 1), with RoHS compliance. These certifications support regulatory compliance, supplier qualification, and safer procurement processes in many industrial facilities and global operations.
Eaton backs the SPM300240S1X with a 15-year warranty from delivery, extending to 20 years if registered on Eaton’s SPD site. This long-term coverage lowers lifecycle costs by reducing replacement frequency and maintenance disruptions, while the standard surge counter provides actionable data to quantify ongoing protection and justify the investment.
