GE - DS16FK Class R Fuse Rejection Kit | Field-Install for 30A/60A DH & DT Safety Switches

GE DS16FK Class R Fuse Rejection Kit — a field-installable fuse clip conversion kit for General Electric (now ABB/Eaton-branded GE) safety switches. The DS16FK converts standard safety switches to accept only Class R fuses, providing an added layer of protection against over-fusing by physically preventing the installation of higher-rated or wrong-type fuses.

Why Choose the GE DS16FK?

The DS16FK is an essential safety upgrade for any facility running GE-style DH or DT series safety switches on 30A or 60A circuits. By converting fuse clips to Class R rejection type, you permanently prevent the installation of fuses with higher interrupt ratings or incorrect sizes — a common cause of equipment damage and arc flash incidents in commercial and industrial electrical systems.

What Is a Class R Fuse Rejection Kit?

A Class R fuse rejection kit replaces or modifies the fuse clips inside a safety switch so that only Class R (RK1 or RK5) current-limiting fuses can be physically inserted. Class R fuses offer superior current-limiting performance compared to older Class H fuses. The rejection feature ensures that once upgraded, the switch cannot accidentally accept a non-current-limiting fuse — protecting downstream equipment and reducing arc flash energy.

Common Applications

• Upgrading legacy GE safety switches from Class H to Class R fusing
• NEC code compliance for current-limiting fuse requirements
• Motor branch circuit protection upgrades
• Arc flash hazard reduction programs
• 30A and 60A safety switch installations on 240V and 600V systems

Installation Note: Always de-energize and verify the switch is in the OFF position before installing. UL Listed for field installation per GE BuyLog specifications. Verify switch series compatibility before ordering.
