Eaton Bussmann mdl-6-1/4-r Glass Tube Fuse 6.25A 250V

Product Description

The EATON BUSSMANN mdl-6-1/4-r is a time-delay glass tube fuse rated at 6.25 amps and 250 volts AC. It measures 0.25 inches in diameter by 1.25 inches in length, fitting the standard 1/4 x 1-1/4 inch miniature fuse form factor. The nickel-plated brass endcaps and glass tube body provide reliable protection in low-amperage circuits. This fuse is designed for applications where brief inrush currents must be tolerated without nuisance tripping, making it a go-to choice for electricians and technicians servicing control circuits, small appliances, and instrumentation panels.

This fuse is suited for residential and light commercial electrical applications where a 1/4 x 1-1/4 inch time-delay fuse is specified. Common install scenarios include HVAC control boards, test equipment, power supplies, and other low-current circuits that draw temporary overcurrent on startup. The time-delay characteristic prevents premature fuse failure caused by motor inrush or capacitive load startup surges. Licensed electricians and HVAC technicians are the typical installers for this type of overcurrent protection device.

Key Features

• Time-delay action tolerates brief inrush currents without nuisance blowing
• Rated 6.25 amps at 250 volts AC
• Standard 0.25 x 1.25 inch glass tube body with nickel-plated brass endcaps
• Interrupting rating of 200 AIC at 250 VAC and 10,000 AIC at 125 VAC
• UL Listed to standard 248-14 (Guide JDYX, File E19180)
• CSA Certified (Class No. 1422-01)

Compatibility

Designed as an OEM-style replacement for 1/4 x 1-1/4 inch time-delay miniature fuses in control panels, HVAC equipment, and instrumentation circuits requiring a 6.25-amp, 250-volt AC rating.

Installation Notes

Always de-energize and lock out the circuit before replacing a fuse. Confirm the replacement fuse matches the amperage, voltage, and time-delay characteristics specified on the equipment label or wiring diagram. Use a fuse puller when removing glass tube fuses from spring-clip holders to avoid breakage. Installation must comply with applicable NEC requirements for overcurrent protection.
