Bussmann FNM-40 - Low Voltage Time-Delay Fuse 40A (32V DC, 10kA AIC)

Bussmann FNM-40 is a low-voltage time-delay fuse designed for circuit protection in 32V DC systems requiring 40A current ratings. This ferrule-type fuse features a single-barrel construction with 0.41-inch diameter and 1-1/2-inch length, weighing 1.2 lb for compact installation. Certified to CE, CSA Class 1422-01, and UL-248-14 standards (Guide JDYX), it provides reliable protection with 10kA interrupting capacity at 250V. The FNM-40 is commonly applied in automotive, marine, and low-voltage DC power distribution systems where time-delay characteristics prevent nuisance tripping during motor starting or transformer inrush conditions.
