Cooper Bussmann FNQ-R-3-2/10 Cc Time Delay Fuse 3.2A

Product Description

The COOPER BUSSMANN FNQ-R-3-2/10 is a Class CC time delay cartridge fuse rated at 3.2 amps, designed for general-purpose overcurrent protection in low-amperage branch circuits and control panels. The rejection feature of Class CC fuses prevents substitution with lower-rated fuse classes, ensuring proper circuit protection integrity. With an interrupting rating of 200 kA at AC RMS, this fuse handles high fault currents safely within its compact cartridge body. Electricians and control panel builders install this fuse in fuse holders sized for CC-class cartridges. Its time delay characteristic allows harmless inrush currents to pass while still protecting against sustained overloads and short circuits.

This fuse is suited for residential and light commercial electrical applications where Class CC rejection-style fusing is specified. Typical installation scenarios include motor control circuits, transformer primaries, and branch circuit protection panels where inrush tolerance is required. The 10.3 mm diameter cartridge body mounts in standard CC-class fuse holders. This part ships in a package quantity of one, with a minimum order quantity of five units per order.

Compatibility

Designed for use in fuse holders that accept Class CC rejection-style cartridge fuses. Verify holder rating and amperage compatibility before installation.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. Always de-energize and lock out the circuit before replacing or inspecting fuses. Confirm the fuse holder is rated for Class CC cartridges and that the circuit voltage and amperage do not exceed the fuse ratings. Do not substitute non-rejection fuses in holders designed for Class CC rejection fuses.
