Bussmann FLQ5 Fuse

FLQ5 is a 5 A time-delay (slow-blow) fuse from Bussmann’s FLQ family, a compact midget cartridge fuse designed for standard control-panel and equipment protection. It is rated for up to 500 VAC with an interrupting rating of 10 kA at 500 VAC and 10 kA at 300 VDC, making it suitable for circuits with inrush currents where a nuisance trip from a fast-acting fuse would be undesirable. The body measures 13/32 in diameter by 1-1/2 in long (10 × 38 mm), the typical FLQ form factor for Bussmann’s midget fuses. This device is UL-listed and CSA-certified, offering verified safety credentials for widely used electrical protection applications. Common applications include protection for electronic control panels and equipment that require a 5 A slow-blow fuse in systems up to 500 VAC, where brief surges can be tolerated without compromising protection. The FLQ family is a long-standing Bussmann line, and the FLQ5 variant is specifically designed to fit standard Bussmann FL-series holders and similar control-circuit configurations.
