Special features
Basic
High surge capacity delivers real-world protection up to 120 kA per phase, reducing the risk of damaging surges and costly outages. Business impact: fewer unplanned shutdowns and lower repair costs, enabling predictable maintenance windows for critical lines in manufacturing and processing plants. Application: ideal for distribution panels and equipment rooms in industrial facilities requiring dependable surge suppression and quick fault isolation. 120/240 V split-phase compatibility ensures seamless integration with standard electrical infrastructure, simplifying installation and reducing retrofit time. Application: data centers, control panels, and machinery rooms where diverse loads share a common power source. NEMA 4 enclosure with an internal circuit breaker provides rugged, weather-resistant protection and built-in isolation. Business impact: safer outdoor and harsh-environment deployments with reduced enclosure penetrations and space savings. Application: outdoor-rated or damp locations in outdoor service entrances and non-sheltered installations. RoHS compliant, UL 1449 and UL 1283, CSA listings guarantee compliance and supplier confidence. Business impact: accelerated procurement cycles and reduced compliance risk across global sites. Compatibility and mounting advantages include a compact single-module design, straightforward panel integration, and compatibility with standard Eaton SPD MAX configurations. Application: retrofit projects and new builds seeking scalable protection. Warranty of 15 years (20 years with registration) supports total cost of ownership and long-term ROI. Business impact: lower lifecycle costs and improved protection resiliency across the facility.

FAQs
Plan for a dedicated mounting space that accommodates the 14.91 in width, 17.5 in height, and 9.3 in depth. The unit weighs 50 lb and uses an internal circuit breaker within a NEMA 4 enclosure, which supports indoor and sheltered outdoor locations. Ensure panel compatibility with a single-module SPD MAX configuration to minimize retrofit complexity and maximize protection coverage.
A 120 kA per phase rating indicates the device can absorb large transient energies without compromising protection performance. This translates to reduced risk of equipment damage during lightning or utility transients, lower repair costs, and less downtime. Pairing this rating with UL 1449 and UL 1283 certifications strengthens regulator compliance and reliability in critical loads.
Yes. The unit is specifically designed for 120/240 V split-phase systems, matching common industrial and commercial power architectures. Its USC/UL listed protection, combined with a rugged NEMA 4 enclosure, makes it appropriate for panel boards, equipment rooms, and outdoor-rated installations where reliable surge suppression is needed.
Key certifications include UL 1449 and UL 1283, CSA Electrical Notice NO. 516 Edition 1, and CSA Std. C22.2 No. 8-M1986. The product is RoHS compliant, which supports environmental and European market requirements. These certifications streamline approvals for electrical systems in various jurisdictions and support safer, compliant installations.
Investing in the SPD MAX series yields ROI through reduced downtime, extended equipment life, and lower replacement costs for surge-damaged devices. The 15-year warranty (20 years with registration) provides long-term protection and predictable ownership costs. Routine inspection and periodic enclosure integrity checks are recommended, with attention to internal circuit breaker status and any protection element replacement needs following utility events.
