## Description

The Eaton Bussmann TCF20 is a 20A, 600VAC/300VDC dual-element, time-delay CUBEFuse designed for high-performance industrial circuit protection. Engineered to meet Class CF and Class J electrical requirements, this fuse features a compact footprint measuring 47.75mm x 19.05mm x 25.4mm. Its dual-element construction provides a minimum 10-second time delay at 500% of the rated current, effectively minimizing nuisance tripping caused by transient surges and temporary overloads while ensuring rapid response to damaging short-circuit faults.

This finger-safe power fuse is rated for an interrupting capacity of 300kA RMS symmetrical (UL) and 100kA DC, providing robust protection in demanding power distribution environments. Constructed with a glass-filled polyethersulfone (PES) case and electroless tin-plated copper alloy terminals, the TCF20 is built for durability within an operating temperature range of -40°C to 80°C. The component is UL Listed (Guide JFHR) and CSA Certified, and it supports Type 2 "No Damage" protection for IEC motor starters. Its design allows for simple 2:1 selective coordination with other Low-Peak Class CC, J, and RK1 fuses, making it a reliable solution for industrial automation, motor control centers, and branch circuit disconnect applications.
