Value Collection BD-29571 RK5 Time Delay Fuse 20A

Product Description

The VALUE COLLECTION BD-29571 is a cartridge-style, time delay fuse rated at 20 amps and classified RK5 for general-purpose overcurrent protection. It measures 2 inches in overall length and 9/16 inches in diameter, fitting standard fuse holders designed for that form factor. The time delay characteristic allows temporary inrush currents to pass without nuisance opening, making it suitable for motor loads and other equipment with high starting currents. The dual-element construction provides both overload protection and short-circuit interruption, with an interrupting rating of 200 kA. This fuse is installed by licensed electricians working on branch circuits, control panels, and industrial equipment.

This fuse is applied in general-purpose electrical distribution and control circuits where RK5 class overcurrent protection is specified. Typical installations include motor branch circuits, control panels, and load centers in commercial and industrial settings. The 20-amp rating and cartridge body make it a common selection for equipment protection in environments requiring a time delay to accommodate motor starting inrush without sacrificing short-circuit response. It meets CSA, UL 198L, and Federal Specification W-F-1814 QPL standards, supporting use in a wide range of code-compliant installations.

Installation Notes

Installation and replacement of branch circuit fuses must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize the circuit and verify absence of voltage with a meter before handling fuses or opening fuse holders. Use insulated fuse pullers rated for the voltage and current of the circuit. Never replace a fuse with one of a higher amperage rating than specified by the equipment manufacturer or circuit design.
