Schneider Electric DRK40 Fuse Rejection Kit 400A Class R

Product Description

The SCHNEIDER ELECTRIC DRK40 is a Class R fuse rejection kit designed for use with F Series General Duty Safety Switches rated at 400 amperes. This kit restricts the fuse mounting to accept only Class R fuses, preventing the installation of lower-rated or non-rejection fuses that could compromise overcurrent protection. It is installed by licensed electricians during service or maintenance of general duty safety switches in commercial and industrial electrical distribution systems. The DRK40 is a compact, factory-matched accessory that ensures the switch assembly maintains its intended protection rating.

This fuse rejection kit is used with F Series General Duty Safety Switches in commercial and industrial applications where consistent overcurrent and short circuit protection is required. General duty safety switches equipped with proper fusing and optional neutral or grounding assemblies may qualify for use as service entrance equipment. The DRK40 supports compliance with those configurations by locking in the correct fuse class at the switch.

Installation Notes

Installation should be performed by a qualified, licensed electrician. De-energize the safety switch and verify the absence of voltage using a calibrated meter before servicing or installing any components. Ensure compliance with applicable NEC requirements for overcurrent device ratings and service equipment configurations. Do not install this kit on switch enclosures that are not rated for Class R fuse rejection applications.
