The Bussmann FNQ-20 is a low-voltage, time-delay fuse designed for branch circuit and feeder protection in industrial control panels and motor circuits. It features a 20A current rating and a 500V AC/DC voltage rating, providing reliable overcurrent protection with a 10kA interrupting rating at its rated voltage. The fuse is constructed as a single-barrel, 1/4" x 1-1/2" (0.41 in x 1.5 in) device with a ceramic body for durability and is certified to UL 248-14, CSA C22.2 No. 248-14, and CE standards. Its time-delay characteristic allows it to withstand typical motor starting currents without nuisance opening, making it suitable for protecting transformers, solenoids, and motor loads across various industrial applications.
