Special features
Standard with surge counter
Feature: 400 kA per phase surge protection delivers robust transient handling for high-energy faults common in industrial power networks. Business impact: elevates system resilience, reduces unexpected equipment failures, and cuts downtime costs during wind, solar, and manufacturing processes. Application: ideal for motor control centers, panel boards, and critical feeders in manufacturing plants and data centers. Feature: 240 delta (4W+G) voltage rating aligns protection with high-leg delta configurations used in older installations. Business impact: minimizes nuisance tripping, ensures correct phase-to-phase protection, and supports reliable operation of energized loads. Application: suitable for facilities with delta-wye distributions and mixed load profiles in process industries. Feature: NEMA 4 enclosure with internal circuit breaker provides rugged protection in challenging environments. Business impact: enables outdoor or damp locations without additional enclosure, reducing integration time and project costs. Application: ideal where environmental sealing and integrated protection are required, such as outdoor substations and warehouse facilities. Feature: Standard with surge counter facilitates event logging for maintenance and regulatory reporting. Business impact: supports proactive asset management, simplifies compliance audits, and improves MTTR when surges are correlated to incidents. Application: valuable for plants with strict uptime goals and traceable surge data for asset health programs. Feature: RoHS compliance with UL 1449 and UL 1283 plus CSA certification ensures regulatory readiness and a solid 15-year warranty (20 years when registered). Business impact: reduces procurement risk, speeds approvals, and improves sustainability profiles across the supply chain. Application: supports projects in automotive, food and beverage, pharma, and general manufacturing environments requiring rigorous safety standards.

FAQs
The SPM400240H3R is designed for straightforward integration into typical industrial panels, featuring a NEMA 4 enclosure with an internal circuit breaker. Its footprint aligns with common panel dimensions, and the unit’s 9.3 in depth, 17.5 in height, and 14.91 in width help planners estimate mounting space. Ensure clearance for service access and the surge counter visibility for monitoring.
This SPD is rated at 240 delta (4W+G), addressing protection needs in high-leg delta configurations. The rating helps prevent phase-to-phase and phase-to-ground transients from compromising protected loads, reducing nuisance trips and extending equipment life in facilities with delta-wye distributions and mixed motor loads.
Yes. The unit is UL 1449 and UL 1283 listed, and certified under CSA Electrical Notice 516 Edition 1 as well as CSA standards. These certifications reflect adherence to nationwide safety and performance requirements, facilitating regulatory approval and supplier qualification in regulated industries.
The surge counter logs transient events as they occur, enabling traceable maintenance records and easier compliance reporting. Facilities can correlate surge activity with equipment performance, optimize preventive maintenance schedules, and demonstrate due diligence during audits without ancillary metering hardware.
The SPD carries a 15-year warranty from the date of delivery, with an extended 20-year term when registered on Eaton’s site. This long-term coverage reduces lifecycle costs, supports budgeting for Long-Term Reliability, and provides protection against unseen failures in mission-critical installations.
