About this item

BP/FRN‑R‑45 FUSETRON® 45A Time‑Delay Cartridge Fuse, 250V (2 Pack) – Bussmann Corporation:

The BP/FRN‑R‑45 FUSETRON® Time‑Delay Cartridge Fuse from Bussmann Corporation is a high‑reliability overcurrent protection device engineered for demanding commercial and industrial electrical applications. Designed as part of the proven FUSETRON® FRN‑R series, this dual‑element Class RK5 fuse provides superior performance in circuits subject to temporary overloads and high inrush currents, such as motors, transformers, and inductive loads.

Rated at 45 amps and 250 volts AC, the BP/FRN‑R‑45 combines extended time‑delay capability with fast, current‑limiting short‑circuit protection. Its dual‑element construction uses separate components for overload and short‑circuit response, allowing brief surge currents to pass without opening the circuit while reacting quickly to damaging fault conditions. This design helps reduce nuisance fuse replacements, minimize downtime, and protect valuable electrical equipment.

The Class RK5 rejection‑type body enhances system safety by preventing the installation of lower‑rated substitute fuses when paired with compatible fuse holders. With a high interrupting rating, the BP/FRN‑R‑45 is well suited for use in power panelboards, motor control centers, and industrial machinery where dependable fault interruption is critical. This retail‑packaged version includes two fuses, making it convenient for maintenance, repairs, and stocked inventory.
