Value Collection BD-29891 Cartridge Time Delay Fuse 4A

Product Description

The VALUE COLLECTION BD-29891 is a glass-body cartridge time delay fuse rated at 4 amps and 250 volts. Time delay fuses are designed to handle brief inrush currents without nuisance tripping, then open the circuit reliably when a true overload or short-circuit condition persists. The glass body allows for quick visual inspection of the fuse element without specialized equipment. At 1.25 inches overall length and 0.25 inches in diameter, this is a standard mini cartridge form factor used across a wide range of control circuits, HVAC low-voltage panels, appliances, and light-duty electrical equipment. Sold in a pack of 5, this fuse is installed by licensed electricians and HVAC technicians.

This fuse is suited for residential and light commercial applications where a time delay characteristic is required to accommodate motor start-up inrush or transformer magnetizing current. Typical installations include control boards, low-voltage HVAC circuits, small appliances, and electronic equipment requiring overcurrent protection at 250 volts or below. The mini cartridge form factor fits standard fuse holders and fuse blocks designed for the 1/4-inch diameter, 1-1/4-inch length form.

Compatibility

Designed as a replacement for standard mini cartridge time delay fuses in 1/4-inch by 1-1/4-inch fuse holders and fuse blocks rated to 250 volts.

Installation Notes

Always de-energize the circuit and verify zero voltage with a calibrated meter before replacing a fuse. This fuse is installed by licensed electricians or HVAC technicians in accordance with applicable NEC requirements. Use a fuse puller when removing or installing cartridge fuses in live-panel fuse blocks to avoid contact with energized components. Confirm the replacement fuse amperage and voltage ratings match the original equipment specification before installation.
