SKU CH-WNRN-B6PBZ

A Class R fuse rejection kit rated 30 A at 600 V AC for heavy-duty safety switches

  • TypeLight Switch
  • Color/FinishWhite
  • Fuse rejection kit prevents incorrect Class R fuse installation
  • 30 A current rating matches 30 A disconnect switches
  • 600 V AC maximum voltage handles heavy-duty circuits
  • CSA certified and UL listed for safety compliance
  • Designed for Series F5 to F7 safety switches

Purpose & Fit

The Square D Fuse Rejection Kit is a heavy-duty accessory rated for 30 A and 600 V AC. It fits 30 A disconnect switches in the F5 to F7 safety-switch series and accepts only Class R fuses. The kit is UL Listed and CSA Certified for code-compliant installations.

Sustained Load Behaviour

Built for heavy-duty duty, the kit maintains its rejection function under continuous 30 A loading without degradation. The Class R restriction prevents incorrect fuse insertion during prolonged operation, keeping the disconnect switch protected at its full 600 V AC rating.

Thermals, Noise & Power

As a passive mechanical component, the kit generates no heat, noise or power draw of its own. It simply enforces correct fuse fitment inside the safety switch, so thermal and acoustic performance depends entirely on the host disconnect and the installed Class R fuse.

Questions about this item

Does the 600 V AC rating mean the kit generates noticeable heat when the 30 A disconnect switch runs continuously?

The kit is a passive fuse-rejection accessory; it adds no active components, so it does not produce additional heat beyond the normal dissipation of the Class R fuse and safety switch contacts.

My panel uses Heavy Duty Safety Switches Series F5 to F7 — does this kit require any extra hardware to install?

No extra hardware is needed; the rejection clips mount directly into the existing 30 A fuse clips of Series F5–F7 switches.

Will the Class R rejection clips work with the original Class H fuses I still have in stock?

No — the rejection feature physically prevents Class H fuses from seating, so only Class R fuses can be used once the kit is installed.
