FNA Time-Delay Supplemental Fuses

Bussmann / Eaton FNA Time-Delay Supplemental Fuses are color-coded by maximum voltage rating and offer a pin indicator for visual indication of the open fuse condition. The dual-element, time-delay performance permits close sizing on control transformers and relays. These 250V_AC fuses are 13/32" x 1 1/2" and use a silver-plated pin for positive, electrical signal activation. The 12A and higher versions feature dual-tube construction. Bussmann / Eaton FNA Time-Delay Supplemental Fuses are ideal for power electronic circuits and inductive load circuits.
