Siemens SSRK34 Class R Fuse Rejection Kit 200A

Product Description

The SIEMENS SSRK34 is a Class R fuse rejection kit rated for 200 amps, designed to retrofit existing fusible disconnect switches and panelboards to accept only Class R fuses. By installing this kit, the panel is mechanically restricted from accepting Class H or other non-rejection fuses, enforcing proper fuse selection and preventing accidental misapplication. The kit is compact and lightweight at 0.044 pounds, with a footprint of approximately 3.937 x 0.787 x 0.787 inches. Electricians install this during service upgrades or code compliance work where Class R fuse enforcement is required.

This rejection kit is suited for residential and light commercial electrical distribution equipment. It is commonly installed in fusible safety switches, disconnects, and loadcenters where the authority having jurisdiction or facility maintenance standards require Class R fuse-only operation. The kit provides a straightforward, low-labor method to bring existing equipment into compliance without replacing the entire disconnect or panelboard enclosure.

Installation Notes

Installation must be performed by a licensed electrician. De-energize and lock out the disconnect or panelboard before beginning work, following NFPA 70E lockout/tagout procedures. Verify the equipment enclosure accepts a Class R rejection insert before proceeding. After installation, confirm the rejection clip seats fully and that a Class H fuse cannot be inserted before restoring power.
