FAQs
The SPM100240S3R is designed for 120/240 V split-phase systems and swings into standard Eaton SPD MAX series panel installations. It fits typical commercial and industrial electrical panels, leveraging a NEMA 4 steel enclosure with an internal circuit breaker for straightforward wiring. The device supports UL 1449 and UL 1283 compliance and includes a surge counter for monitoring protection history in service panels and data centers.
This model delivers 100 kA per phase surge protection, which effectively clamps high-energy transients before they reach PLCs, drives, and controllers. The robust rating minimizes voltage excursions during lightning events or switching operations, preserving processor reliability, reducing maintenance costs, and extending asset life across manufacturing lines and critical facilities.
The unit carries UL 1449 and UL 1283 listings, CSA certification, and RoHS compliance. These certifications ensure regulatory alignment for commercial and industrial deployments, support safer procurement decisions, and help satisfy internal and external audits across data centers, healthcare facilities, and process automation environments.
By preventing transient-induced failures, the SPM100240S3R reduces downtime, protects sensitive equipment, and lowers repair costs. The built-in surge counter supports proactive maintenance planning, enabling scheduled inspections before failures occur. Combined with the long warranty, this translates to a lower total cost of ownership for asset-intensive facilities.
Plan for a 9.3 in length, 14.91 in width, and 17.5 in height footprint with a 50 lb weight. The NEMA 4 steel enclosure and internal circuit breaker simplify mounting and safety isolation. Ensure adequate panel space and service clearances in accordance with local electrical codes, allowing easy access for monitoring the surge counter and performing routine maintenance.
