Square D RFK03L Safety Switch Fuse Clip Kit

Product Description

The SQUARE D RFK03L is a fuse clip kit designed as a replacement accessory for heavy-duty safety switches. Fuse clip kits restore proper fuse retention inside a safety switch enclosure when clips become worn, damaged, or corroded over time. The RFK03L ships as a single kit and is installed directly inside the switch body, ensuring secure contact between the fuse and the switch's internal bus. Licensed electricians and qualified service technicians handle this type of repair as part of routine safety switch maintenance. At 0.02 pounds and compact dimensions, the kit is a simple drop-in service part that gets a switch back to reliable operation without a full enclosure replacement.

This fuse clip kit is suited for maintenance and repair applications on heavy-duty safety switches found in commercial and industrial electrical distribution systems. Typical install scenarios include field repairs where original fuse clips have failed due to arcing, heat cycling, or mechanical fatigue. The kit is sized for service work where replacing individual internal components extends the service life of the existing switch enclosure.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lockout/tagout the circuit at the upstream overcurrent device before opening the safety switch enclosure. Verify that the replacement clips are fully seated and making firm contact before closing the enclosure and restoring power. Do not energize the switch with fuses installed until the clip installation is confirmed complete and the enclosure is properly closed and latched.
