About this item

Bussmann FRN‑R‑30 — 30A Dual‑Element Time‑Delay Class RK5 Fuse:

The FRN‑R‑30 is a dual‑element, time‑delay, current‑limiting Class RK5 fuse designed for industrial and commercial electrical systems. Its construction allows it to tolerate temporary inrush currents—such as those produced by motors and transformers—while still providing excellent protection against overloads, ground faults, and short‑circuits. This makes it ideal for motor circuits, power panelboards, and machinery disconnects.

Key Features

  • Dual‑element time‑delay design, ideal for circuits with motor or transformer inrush currents. 
  • Time‑delay performance: 8 seconds minimum at 500% rated current (for the 0–30A range). 
  • Current‑limiting Class RK5 fuse improves short‑circuit protection and limits damage during high‑fault events.
  • Non‑indicating standard version (indicating versions available in the FRN‑R family).
  • Rejection‑type fuse, ensuring proper installation only in Class R fuse holders for added safety.

  • Power panelboards 
  • Combination motor starters 
  • Machinery disconnects 
  • Circuits requiring time‑delay tolerance for inrush, but strong short‑circuit protection.

This fuse is suitable for industrial facilities, commercial electrical systems, and equipment requiring selective coordination and durable overload protection.
