Eaton Specification Sheet - BP/FNM-15
Time-delay design delivers controlled protection by tolerating brief inrush without delaying fault clear, translating to fewer nuisance trips and smoother startup for motors and lighting ballasts. In practice, engineers see measurable uptime gains when replacing fast-acting fuses with a time-delay variant on circuits with brief spikes. The BP/FNM-15 strikes a balance with a 15 A rating and a 10 kAIC interrupt capacity at 250 V, offering robust protection while keeping nuisance trips manageable. Dual ferrule-end terminations simplify panel installation, enabling reliable connections in terminal blocks and ensuring compatibility with common ferrule wiring. The fiber-tube construction and standard blister packaging support straightforward replacement in field and shop environments, reducing downtime. RoHS compliance and standard blister packaging help minimize regulatory risk and streamline procurement for OEMs and service teams.

FAQs
BP/FNM-15 is ideal for general purpose and lighting circuits within electrical panels. Its 15 A rating, 250 V operating range, and 10 kAIC interrupt capacity provide reliable protection for control panels, meter circuits, and lighting sub-panels while tolerating startup surges. The ferrule-end connections simplify panel integration in typical terminal blocks and service enclosures.
The BP/FNM-15 uses a time-delay (slow-blow) design that tolerates brief inrush currents common to motors, lighting ballasts, and meter circuitry. This minimizes nuisance trips during startup, improving uptime and reducing unplanned maintenance while maintaining full protection against short circuits and overcurrents.
Yes, BP/FNM-15 is RoHS compliant, which helps meet environmental and regulatory requirements in many markets. The data sheet notes compliance and recommends checking with Eaton for market-specific certifications beyond RoHS. For projects requiring additional approvals, consult the Eaton datasheet and regional compliance resources.
BP/FNM-15 utilizes ferrule-end terminations on both ends for straightforward connection to ferrule-wired components. It is packaged in a standard blister pack and features a fiber tube fuse body, which supports easy handling, field replacement, and reliable seating in compact control panels.
The fuse is rated for 15 A at 250 V with a 10 kAIC interrupt rating, suitable for general purpose circuits, lighting circuits, and meter circuits. Its time-delay characteristic and dual-element design make it well-suited for environments with brief startup surges, providing dependable protection with manageable downtime.
