About this item

Bussmann BP/FRN‑R‑20ID — 20A Time‑Delay Fuse (250V, 2‑Pack):

The Bussmann BP/FRN‑R‑20ID is a high‑performance, dual‑element, time‑delay fuse engineered for demanding electrical environments where reliability and selective overload protection are essential. Part of Bussmann’s well‑known Fusetron FRN‑R Series, this fuse is specifically built for circuits subject to temporary inrush currents—such as those found in motors, transformers, and inductive loads—allowing them to start and operate properly while still providing robust protection from sustained overloads and short‑circuit events.

This 2‑count (2CD) pack offers consistent current‑limiting performance and features an indicating design, meaning the fuse label darkens when it has opened. This allows quick visual troubleshooting, helping reduce system downtime in commercial, industrial, and facility power systems. With dual‑element construction, a high interrupt rating, and broad RK5‑class compatibility, the BP/FRN‑R‑20ID delivers long‑lasting, dependable protection across a wide range of electrical installations.

Key Features

  • 20‑Amp Dual‑Element Time‑Delay Protection, ideal for circuits that experience temporary overloads such as motor startup surges. 
  • Class RK5 Current‑Limiting Fuse, reducing let‑through energy during short‑circuit conditions to help protect sensitive equipment. 
  • Indicating Design — the fuse label darkens when blown, simplifying maintenance and reducing troubleshooting time.
  • Time‑Delay Performance rated for approximately 8 seconds at 500% of the fuse’s nominal current, ensuring tolerance for temporary inrush loads. 
  • Dual‑Element Construction provides advanced overload and short‑circuit protection in one fuse, enhancing system reliability. 
  • High Interrupting Ratings suitable for heavy‑duty industrial applications (up to 200kA AC). 
  • Ferrule‑End Cartridge Design for quick, secure installation into compatible fuse blocks. 
  • UL and CSA Listed, ensuring recognized safety and performance in commercial and industrial electrical systems.
