Fuse Rejection Kit 100 A

This Class R fuse rejection kit is designed for 100 A disconnect switches. It ensures only Class R fuses can be installed in compatible equipment. Electrical contractors and maintenance teams use it to meet code requirements for heavy-duty circuits. The kit works specifically with Class 9422 disconnect switches.

100 A 600 V capacity

The kit supports a current rating of 100 A at a maximum of 600 V AC. It provides the correct rejection feature for heavy-duty Class R fuses in this range. Circuits exceeding these ratings will require different rejection hardware. The kit does not alter the ampere or voltage limits of the switch itself.

CSA Certified UL Listed build

The kit carries CSA certification and UL Listing for verified safety compliance. It mounts directly into Class 9422 disconnect switches without modification. The rejection mechanism physically blocks incorrect fuse classes from insertion. This helps prevent downgrading protection on critical heavy-duty circuits.
