Cooper Bussmann ATM-FMX-EK 30 Piece Emergency Fuse Kit

Product Description

The COOPER BUSSMANN ATM-FMX-EK is a 30-piece emergency fuse assortment designed for fast, on-the-job fuse replacement in automotive and light-duty electrical applications. The kit combines two common fuse formats — ATM mini blade fuses and FMX maxi blade fuses — along with an FT-3 fuse tester and puller tool, giving technicians everything needed to diagnose and replace blown fuses without a separate tool run. The compact package dimensions are 0.04 inches H x 0.196 inches W x 0.183 inches L, and the complete kit weighs 0.2 pounds. This is a practical service and diagnostic kit kept in a vehicle, service van, or shop toolbox.

The ATM-FMX-EK is suited for automotive electrical service, fleet maintenance, and mobile equipment repair where ATM and FMX blade fuse formats are standard. The kit includes five each of ATM-10, ATM-15, ATM-20, ATM-25, and ATM-30 amp mini blade fuses, plus one each of FMX-20, FMX-30, FMX-40, and FMX-50 amp maxi blade fuses. The included FT-3 fuse tester and puller eliminates the need for a separate continuity tester when tracing fuse failures in fuse blocks or junction boxes.

Compatibility

Designed as a replacement fuse assortment for vehicles and equipment using standard ATM mini blade and FMX maxi blade fuse formats, as specified in the kit contents.

Installation Notes

Fuse replacement and electrical diagnosis should be performed by a qualified technician following applicable electrical safety procedures. Always power down or disconnect the battery before accessing fuse blocks or junction boxes when possible. Use the included FT-3 tester to confirm a fuse is blown before replacement rather than replacing fuses by sight alone. Never substitute a higher-amperage fuse for a blown one, as this can damage wiring or cause a fire hazard.
