Cooper Bussmann FNA-6/10 Cartridge Time Delay Fuse 0.6A 250V

Product Description

The COOPER BUSSMANN FNA-6/10 is a cartridge-style, time-delay fuse rated at 0.6 amps and 250 volts with an overall length of 1.5 inches. It features a dual-element design and a pin indicator that gives a visual signal when the fuse has opened, reducing troubleshooting time during service calls. Rated for an interrupting capacity of 35 amps at 250 volts, this fuse is built for low-amperage branch circuit and control circuit protection. It mounts in a standard fuse holder and is identifiable by its green body. Licensed electricians and controls technicians are the typical installers for this type of component.

This fuse is suited for use in control panels, HVAC equipment control circuits, small appliances, and instrumentation where time-delay protection is required on low-current circuits. The time-delay characteristic allows momentary inrush currents to pass without nuisance opening, making it appropriate for circuits with small motor loads or transformer primaries operating at 250 volts or below. It is packaged individually and ordered in single-unit quantities.

Key Features

• Time-delay (dual-element) design tolerates brief inrush currents without nuisance trips
• Pin indicator provides visual confirmation of a blown fuse for fast fault diagnosis
• 0.6A rating suits low-current control and instrumentation circuits
• 250V rated with 35A interrupting capacity at 250 volts
• Compact 1.5-inch overall length fits standard cartridge fuse holders
• CE Certified, CSA Certified, and UL Listed for broad compliance coverage

Compatibility

Designed as an OEM-style replacement for cartridge fuse holders accepting 1.5-inch time-delay fuses in low-amperage control circuit applications.

Installation Notes

Installation should be performed by a qualified electrician or controls technician in accordance with applicable NEC requirements. Always de-energize and lock out the circuit before removing or replacing a fuse. Verify the replacement fuse amperage and voltage ratings match the circuit requirements exactly before inserting into the fuse holder. Do not substitute a non-time-delay fuse in circuits specified for time-delay protection.
