Value Collection BD-29556 RK5 Cartridge Time Delay Fuse 3A

Product Description

The VALUE COLLECTION BD-29556 is a cartridge-style, time delay fuse rated at 3 amps and classified as RK5. It is designed to protect electrical circuits from overcurrent conditions while tolerating brief inrush current spikes that occur during motor starts and transformer energization. The fuse body measures 2 inches in overall length and 9/16 inches in diameter, fitting standard fuse blocks and holders that accept Class RK5 cartridge fuses. With a dual-element construction, the BD-29556 provides both overload protection and short-circuit interruption up to 200 kiloamps interrupting capacity. Licensed electricians and industrial maintenance technicians typically install this fuse in branch-circuit and feeder applications.

This fuse is suited for residential, commercial, and light industrial electrical systems where time delay performance is required to allow motor loads, HVAC compressors, or transformer circuits to start without nuisance opening. The RK5 classification indicates it fits Class RK5 fuse holders and rejection-style fuseholders that accept RK5 but reject lower-rated RK1 fuses. It is commonly installed in disconnect switches, motor control centers, and load centers requiring a dual-element time delay overcurrent device. The 3-amp rating makes it appropriate for small motor and control circuit applications.

Key Features

• Dual-element construction provides time delay for motor inrush current plus fast response to short-circuit faults
• 200 kiloamp interrupting capacity for high fault-current environments
• Class RK5 fuse classification fits standard RK5 cartridge fuse holders
• 2 inches overall length and 9/16 inches diameter for easy replacement in standard blocks
• Meets CSA, UL 198L, and Federal Specification W-F-1814 QPL requirements

Compatibility

Designed as an OEM-style replacement for Class RK5 cartridge fuse applications requiring a 3-amp, time delay, dual-element fuse in a 2-inch by 9/16-inch form factor.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and lock out the circuit before removing or installing a fuse. Use an approved fuse puller when handling cartridge fuses to avoid arc flash and contact hazards. Verify the fuse holder is rated for Class RK5 cartridge fuses before installation.
