Cooper Bussmann BP/MDL-3 Time Delay Glass Fuse 3A 250V

Product Description

The COOPER BUSSMANN BP/MDL-3 is a time-delay glass tube fuse rated at 3 amps and 250 volts, sold in a 2-pack carded format. MDL-type fuses are designed for electronic circuits that experience harmless inrush currents at startup, where an instantaneous fuse would nuisance-trip. The glass tube body allows visual inspection of the element without tools. This fuse is a standard solution for protecting low-voltage electronic equipment, control boards, and instrument circuits in residential and light commercial applications. Licensed electricians and HVAC technicians are the typical installers.

MDL-type time-delay fuses are used in electronic control panels, HVAC control circuits, small motors, and instrument enclosures where temporary inrush current must be tolerated without opening the circuit. The 250-volt rating makes this fuse suitable for use across a wide range of single-phase electronic applications. The carded 2-pack format is convenient for service technicians who carry spares in the field.

Key Features

• Time-delay element tolerates startup inrush without nuisance tripping
• Glass tube body allows quick visual confirmation of fuse condition

• MDL type — designed for electronic and instrument circuit protection
• Carded 2-pack format suited for field service use

Compatibility

Designed as an OEM-style replacement for MDL-type time-delay glass tube fuses used in electronic control and instrument circuits rated up to 250 volts and 3 amps.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with applicable NEC requirements. Always de-energize and lock out the circuit before removing or replacing a fuse. Confirm the replacement fuse matches the amperage and voltage ratings of the original before reinstalling. Never substitute a higher-amperage fuse to bypass a repeated opening condition — diagnose the underlying fault first.
