The BP/FNM‑30 from Bussmann Corporation is a time‑delay (slow‑blow) cartridge fuse designed to provide dependable overcurrent protection for low‑voltage circuits that experience high inrush or startup currents. As part of the trusted Bussmann FNM series, this fuse is engineered to allow temporary current surges without nuisance opening, while still protecting equipment from sustained overloads and fault conditions.

Rated at 30 amps and 32 volts, the BP/FNM‑30 is well suited for applications requiring fast response combined with time‑delay characteristics. Its dual‑element design helps manage momentary current spikes common in motors, transformers, solenoids, and other inductive loads, making it a reliable choice for service, replacement, and maintenance use.

The BP/FNM‑30 features a standard midget cartridge size (13/32 in × 1‑1/2 in) for compatibility with common fuse holders and blocks. Supplied in a 2‑count retail card, this fuse is ideal for technicians and maintenance professionals who need reliable protection components readily available.
