Two-module construction provides a robust protection margin, delivering up to 320 kA per phase for 240 V Delta (3W+G) systems. This arrangement strengthens protection for drives, PLCs, and sensors and supports future expansion without swapping hardware, translating to less downtime and lower total cost of ownership. The NEMA 4 enclosure with an internal terminal breaker simplifies installation and field maintenance, reducing wiring complexity and panel footprint while enabling safe operation in both indoor and harsh environments. A standard surge counter offers immediate visibility into surge events, enabling proactive maintenance planning and reliability metrics that inform spare-part strategies and asset management. Certifications and RoHS compliance streamline procurement and audits, ensuring your automation cabinets meet regulatory requirements with reduced risk. Finally, the 15-year warranty (20 years with registration) reinforces long-term reliability for critical equipment such as drives and machine controls.
