Time-delay, dual-element current-limiting design reduces nuisance tripping during motor startup and brief inrush events, delivering smoother equipment operation and lower maintenance costs. The business impact is fewer production interruptions and extended motor life in fans, pumps, and conveyors, enabling reliable uptime in food processing, packaging, and material handling applications. Indicating fuse capability provides immediate, at-a-glance fault location, speeding maintenance and minimizing downtime during outages. This translates to faster repair cycles and reduced labor costs in mission-critical facilities like data centers or manufacturing lines. UL Listed and RoHS compliant certification ensures regulatory alignment and easier procurement across multi-site operations, reducing vendor complexity and audit risk. Compatibility with blade-end connections and finger-safe housing simplifies retrofits and new installations, improving safety and installation time. The compact form factor and standard packaging support easy shipping, stocking, and field service, lowering total cost of ownership in industrial environments. Designed for coordination with TCFH200N and CCP2-3-200CF, it supports selective protection strategies that minimize device replacement and maximize system reliability.
