A Bay-O-Net fuse is ideal for use in a two-fuse protection scheme with a current-limiting backup fuse. You can also request a quote on any of the RTE Fuses using our quote form. Normal fuse sizing: 1.5 Amps (135% of full load current taken to the next higher standard rating) Ambient Temperature: 65C Re-rating: Re-rating: 2 Amps (130% of normal fuse rating) Conversely, when a fuse is intended to be used in extreme low temperature conditions, the fuse must have a lower rating than that in normal conditions. The chart below provides a visual reference for the various sizes of the Bussmann series fuse families. You can verify with ABB, but I doubt it is necessary to change the current-limiting fuse. eaton:resources/marketing-resources/catalogs, eaton:product-taxonomy/medium-voltage-power-distribution-control-systems/utility-fuses/transformer-protection-devices. endobj 0000049779 00000 n
