Bussmann BP/FRN-R-25 25A Fusetron Time-Delay Dual‑Element Fuse – UL Listed 250V (2-Pack)

Overview

Discover the Bussmann BP/FRN-R-25, a heavy‑duty time‑delay fuse designed for motor protection in demanding environments. This UL Listed Class RK5 device blends dual‑element design with current‑limiting features to address both startup surges and sustained overloads with calm reliability.

Engineered for dependable performance in commercial and industrial circuits, it balances protection with practical operation. The dual‑element construction enables fast response to faults while accommodating brief inrush, helping prevent motor burnout during transient conditions. In fault scenarios, the fuse can activate in as little as 0.004 seconds, adding an extra layer of safety for high‑current events.

Key Benefits and How It Helps

• Heavy‑duty, dual‑element time‑delay protection for motors and main panels
• Supports motor start‑ups by tolerating brief surge currents while guarding against overloads
• High‑performance short‑circuit and overload protection via dual elements
• Suitable for general lighting or electric heating circuits when used as a non‑fuse option
• Provides motor overload, ground fault, and short‑circuit protection
• Assists in selective coordination to reduce blackout impact
• Can handle temporary motor overloads and surge currents with robust protection
• Resilient against low‑level overcurrent while accommodating startup inrush

Practical Considerations

• Compatibility with Class H, Class K, or Class R fuse blocks thanks to the end cap design
• UL Listed Class RK5 with broad ratings, including 250V applications
• Available in a range of sizes and amp ratings to fit diverse motor and circuit needs
• Two fuse types exist to cover general purpose and heavy‑duty scenarios; select the right option for your system

In use, this fuse supports motor protection workflows without locking out everyday operation, offering a balance between protection and uptime. While it does not guarantee specific results, it is designed to reduce the risk of motor burnout during overloads and single‑phasing, while allowing a controlled startup surge. For installers and engineers, the BP/FRN-R‑25 provides a reliable, UL‑listed option within the Bussmann range for protecting motors and branch circuits up to the rated voltage and current.
