Ferraz Shawmut R622 Fuse Reducer 600V Class R

Product Description

The FERRAZ SHAWMUT R622 is a Class R fuse reducer rated for 600 volts, designed to adapt larger fuse holders to accept smaller Class R fuses. Fuse reducers of this type are used when a fuse holder is sized for a larger ampere rating than the replacement fuse requires, allowing the installer to maintain proper overcurrent protection without replacing the entire fusible disconnect or panel. The R622 is suited for industrial, commercial, and residential electrical applications where Class R fuse compatibility is needed within an existing 200- to 600-amp fuse holder configuration.

This fuse reducer is appropriate for use in fusible disconnect switches, panelboards, and similar overcurrent protection equipment rated at 600 volts. It is intended for use within the 200 to 600 ampere fuse holder size range and is compatible with Class R fuse formats. Licensed electricians and qualified electrical contractors are the typical installers for this type of component in branch circuit and feeder overcurrent protection assemblies.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. Always de-energize and lock out the disconnect or panel before removing or installing fuse reducers or fuses. Verify that the fuse holder voltage and ampere rating are compatible with the reducer before installation. Do not use fuse reducers to bypass or circumvent the original overcurrent protection design of the equipment.
