Time-delay, dual-element Class CF fuse provides current limiting with controlled response to overloads, reducing nuisance trips while protecting sensitive electronics. This translates to lower maintenance costs and improved equipment availability in production lines and control panels. The 1 A rating and 600 Vac / 300 Vdc voltage capability enable use in small branch circuits and mixed-voltage applications, simplifying inventory and wiring. With a 300 kAIC interrupt rating at 600 Vac and 100 kAIC at 300 Vdc, it delivers robust protection during short-circuit events in high-energy systems, increasing equipment longevity and safety. The blade end connection and 35 mm DIN rail mounting simplify installation in standard enclosures, speeding commissioning and maintenance. Finger-safe construction and non-indicating operation reduce risk during handling and routine inspections, while compatibility with TCFH30N and CCP2-3-30CF devices expands system interoperability for modular protection architectures.
