Bussmann Low-Peak® Class RK1 Time-delay fuse comes with an element window to visually inspect blown element and is rated at 40 Amps/600 VAC/300 VDC. It has an interrupt rating of 300 kilo-Amps VAC RMS and 100 kilo-Amps VDC. Fuse offers a time-delay of minimum 10 seconds at 500% of rated current providing ultimate protection. It features ferrule ends and can be mounted on a holder with clip termination. Its time-delay characteristics allow 130% FLA sizing for back-up motor overload protection and single-phasing protection. It measures 1.060 Inch x 5.500 Inch. Dual-element fuse can be used as a time-delay or a slow-blow fuse making it economical. Limits current for maximum short-circuit protection and reduced arc flash hazard.
