300 kA per phase protection translates to robust transient handling, reducing equipment wear and unexpected downtime in motor drives, PLCs, and control panels. The business impact is lower maintenance costs and improved process uptime in manufacturing facilities and data centers. The 240V delta high-leg (4W+G) configuration ensures compatibility with common four-wire delta systems found in industrial power distribution, enabling straightforward integration without custom wiring or adapters. The NEMA 4 enclosure with an internal circuit breaker provides rugged outdoor or washdown-ready protection and simplifies servicing, minimizing panel creep and eliminating external accessories. The standard surge counter offers real-time visibility for maintenance planning and compliance reporting, streamlining facility audits and asset management. RoHS compliance and multiple certifications (UL 1449, CSA) support regulatory readiness and safer procurement decisions, while the long warranty enhances total cost of ownership for the SPD MAX family.
