Special features
Basic
The two-module Max series design delivers high-energy protection while enabling serviceability without full panel disassembly. This structure translates to faster diagnostics and reduced downtime during maintenance windows. The 400 kA per phase rating supports large transient events, safeguarding sensitive drives, PLCs, and motors in manufacturing lines. NEMA 4X enclosure with internal circuit breaker offers weatherproof protection and quick isolation, making it suitable for outdoor cabinets and damp environments while reducing the need for additional enclosures and improving safety compliance. Voltage rating of 240 delta (4W+G) systems ensures compatibility with common industrial power distribution schemes, enabling straightforward integration into existing panels and minimizing modification costs. RoHS compliance and robust CSA/UL certifications reduce regulatory and traceability risks, supporting safer procurement and smoother audits across facilities. The 15-year warranty (20 years with registration) lowers total cost of ownership by extending asset protection and simplifying lifecycle planning. Engineers gain predictable maintenance cycles and improved asset longevity when deploying this SPD in mission-critical networks.
