Product Description
RS PRO 420-101 Ceramic Cartridge Fuse is a 3.15A FF super fast acting fuse designed for circuit protection in electrical and electronic systems operating at 250V AC. It features a durable ceramic body measuring 5 mm in diameter and 20 mm in length, making it suitable for standard cartridge fuse holders.
This high breaking capacity fuse (HBC) is specifically engineered to provide ultra rapid response (FF rating) which is essential for protecting semiconductor devices such as thyristors, diodes, and transistors from overcurrent damage. The ceramic material body ensures it operates reliably at higher temperatures and offers enhanced safety.
Commonly used in industrial, commercial, automotive, and home electrical applications, this fuse safeguards equipment including motors, air conditioners, refrigerators, and pumps. Unlike circuit breakers that can be reset, this fuse provides an economical and faster reaction by breaking the circuit permanently upon a fault condition and requires replacement after blowing.
The cartridge fuse’s cylindrical shape and miniature 5 x 20 mm dimensions make it ideal for installation on boards and panels where circuit protection is critical. Compliance with RoHS and UL ensures the fuse meets safety and environmental standards.
