Bussmann NSNBC01 Fuse

The Bussmann NSNBC01 fuse is the FNQ-30 time-delay midget fuse, rated 30 A at 500 V AC, designed for circuits subject to inrush currents such as motor control panels and transformers. The compact body measures 13/32 in (0.406 in) diameter by 1-1/2 in long, with ferrule-end terminations on both ends and nickel-plated bronze endcaps, providing an interrupt rating of 10 kA at 500 VAC. This non-indicating fuse belongs to Eaton Bussmann's FNQ series and is specified for time-delay protection to withstand brief surges without nuisance blowing. The NSNBC01 designation indicates a 10-pack packaging configuration for bulk replacement. Typical approvals cited on distributor pages include UL 248-14 and CSA Class 1422-01, with CE listings noted by some inventories. The FNQ-30 operates within a 500 VAC system, offering a controlled 30 A continuous rating and compatibility with standard FNQ-30 footprints in control circuits and motor-related protection schemes.
