Bussmann Fuse Kit: FNQ-R/KTK-R/LP-CC, 45 Fuses Included, 1/2 to 30 A, CC

These fuse kits include midget fuses for noncurrent-limiting, small-interrupt applications and UL Class CC fuses for current-limiting, high-interrupt applications. They're packed in a storage case for organizing and protecting the fuses. Midget fuses supplement the primary branch-circuit fuse or breaker and provide backup overcurrent protection for lighting, solenoid, motor, and transformer circuits. Also known as 5AG fuses, they have lower interrupting ratings than branch-circuit protectors. Midget fuses are noncurrent-limiting, so they won't limit exposure to the full magnitude and duration of an overcurrent. UL Class CC fuses provide overcurrent protection of branch circuits, control circuits, lighting, transformers, and general loads. Their rejection feature ensures a match with Class CC rejection fuse blocks and holders that prevent midget fuses from being installed. Class CC fuses are the smallest 600VAC, 200kA IR fuses approved for branch circuits. They are current-limiting to prevent electrical damage by disconnecting circuits before they're exposed to the full magnitude and duration of an overcurrent.

Fuse kits include multiple fuses of different styles, series, or amperage ratings for use in new installations or as replacements for blown or faulty fuses. Also called fuse service kits, these assortments help reduce downtime by providing a supply of commonly used fuses for maintaining overcurrent protection on electrical systems and equipment. They may also include tools to assist with fuse removal and replacement.
