Eaton BP/FNM-20 Time Delay Cartridge Fuse 20A 2-pack

Product Description

The EATON BP/FNM-20 is a Fusetron FNM series time delay cartridge fuse rated at 20 amps, sold as a 2-pack. It is a general-purpose fuse designed for circuits that experience high inrush current during motor startup. The time delay characteristic allows the brief surge of a motor starting to pass without opening the fuse, while still providing protection against sustained overloads that would otherwise cause damage or create a fire hazard. This fuse is UL Listed and is a standard tool-of-the-trade item installed by licensed electricians and qualified service technicians.

This fuse is well suited for residential and commercial applications where motor loads demand reliable overcurrent protection. Common installation points include spa control panels, pool pump circuits, and other commercial motor-driven equipment. The time delay design prevents nuisance tripping during normal startup while maintaining protection during true fault conditions. Electricians and pool and spa service technicians frequently specify this fuse type when servicing or replacing overcurrent protection in these systems.

Key Features

• 20-amp time delay rating allows motor inrush current to pass without nuisance opening
• Opens under sustained dangerous overload conditions to protect downstream equipment
• Cartridge form factor fits standard fuse holders designed for this series
• UL Listed for general-purpose overcurrent protection
• Sold as a 2-pack for convenient on-hand stock
• Suitable for high inrush applications including spa and pool pump circuits

Compatibility

Designed as a general-purpose time delay cartridge fuse for use in circuits serving spa panels, pool pumps, and other commercial motor equipment that require an FNM-series fuse holder. Specific compatible fuse holder compatibility should be confirmed against the fuse holder manufacturer specifications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for overcurrent protection. Always de-energize and lock out the circuit before removing or installing fuses. Confirm the fuse holder is rated for cartridge fuses of this type and amperage before installation. Do not substitute a higher-amperage fuse in an attempt to eliminate nuisance openings, as this removes essential circuit protection.
