FAQs
The TCF80 uses chassis mounting on a 35 mm DIN rail with blade-end connections, and it includes a fuse indicator for straightforward status checks. This combination simplifies retrofitting into existing control panels, minimizes wiring changes, and accelerates commissioning while maintaining reliable protection for motor circuits.
The TCF80 is rated 80 A with a voltage rating of 600 Vac / 300 Vdc. It provides an interrupt rating of 100 kAIC at 300 Vdc and 300 kAIC at 600 Vac, making it suitable for high-energy fault conditions. It also supports 50–60 Hz operation to align with most industrial systems.
Yes. The time-delay, dual-element Class CF design tolerates startup inrush while delivering selective protection. This reduces nuisance trips and helps prevent unnecessary disconnections of motors and drives, improving uptime in manufacturing and process environments.
The TCF80 is UL Listed and CSA Certified, with CE marking and RoHS compliance. These certifications support regulatory approval across regions, streamline audits, and simplify procurement for global OEMs and integrators working on multi-region machinery.
Choose an 80 A TCF fuse with the same voltage rating for consistent protection coordination. Use the fuse indicator to verify status during maintenance and replace only with the same model (TCF80) to preserve coordination. Maintain clean DIN-rail mounting, inspect blade-end connections, and verify compliance markings during service windows.
