Bussmann FNQ-R-1-1 4 LIMITRON Fuse

Bussmann FNQ-R-1-1/4 Limitron is a Class CC, time-delay, dual‑element current‑limiting fuse from the LIMITRON FNQ‑R family. It is rated for 1.25 A at up to 600 V AC and provides an interrupting rating of 200 kA at 600 VAC. The compact body measures 10.3 mm in diameter by 38.1 mm long (about 13/32 in by 1-1/2 in) and fits standard Class CC fuse holders in electrical panels and industrial distribution. The FNQ‑R fuse features a rejection‑style design to prevent incorrect substitutions and is suitable for protecting control transformers and other control‑circuit equipment, as well as branch circuits in electrical installations where inrush currents are expected but fast clearing is required. As part of the LIMITRON line, it combines time‑delay behavior with current‑limiting protection to accommodate inrush currents while safeguarding downstream equipment.
