Cooper Bussmann JJS-60 Class T Cartridge Fuse 60A 600V

Product Description

The COOPER BUSSMANN JJS-60 is a Class T fast-acting cartridge fuse rated at 60 amps and 600 volts AC. It provides overcurrent protection with a 200 kA interrupting rating at AC RMS, making it suitable for high-fault-current environments. The cartridge body measures 20.60 mm in diameter and 39.70 mm in length, mounting into a standard fuse holder. Licensed electricians and industrial maintenance technicians install this fuse in branch-circuit and equipment-protection applications where a compact, high-interrupting-capacity general-purpose fuse is required.

The JJS-60 is designed for general-purpose electrical protection in both commercial and light industrial settings. Its Class T form factor fits dedicated Class T fuse holders and panelboards. The small physical footprint relative to its amperage and interrupting rating allows it to be used in space-constrained enclosures and switchgear where other fuse classes may not fit. It is appropriate for motor branch circuits, feeder circuits, and equipment protection panels where fast-acting response to overcurrent conditions is needed.

• Compact cartridge body: 20.60 mm diameter, 39.70 mm overall length
• Mounts in standard Class T fuse holders
• CE Certified, CSA C22.2 No. 248.15 Class 1422-02 Certified, and UL Listed 248-15 Class T Guide JDDZ

Compatibility

Designed for use in Class T fuse holders rated for 600-volt, 60-amp fast-acting cartridge fuses. Specific holder compatibility should be verified against the holder manufacturer's amperage and class ratings before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and lock out the circuit before removing or replacing a fuse. Use an insulated fuse puller rated for the voltage class when extracting or seating the cartridge in its holder. Verify that the replacement fuse amperage and class match the circuit's overcurrent protection requirements exactly before restoring power.
