Eaton BP/S-20 Time-delay Plug Fuse 20A 125V 2-pack

Product Description

The EATON BP/S-20 is a Fustat S-Type dual-element, time-delay plug fuse rated at 20 amps and 125 volts AC with a 10,000 amp interrupting capacity (AIC). This pack includes two fuses. The dual-element design allows the fuse to withstand repeated motor starting surges without nuisance opening, while still providing fast response to sustained overloads and short circuits. The rejection base is a tamper-resistant feature that physically prevents substitution with a higher-amperage fuse. An oversized clear window gives technicians a direct visual indicator of fuse condition without removal. This fuse is UL listed and sold as a 2-pack.

The BP/S-20 is designed for circuits that power motor-driven equipment, where high inrush current at startup is normal. Typical applications include residential and light commercial air conditioners, furnace blower motors, swimming pool pumps, deep freezers, and any branch circuit where motors cycle on and off frequently. The S-Type rejection base fits Type S fuse holders and Edison-base adapter sockets, making it a standard replacement in service panel and load center applications across HVAC, plumbing pump, and pool equipment installations.

Key Features

• Dual-element, time-delay construction tolerates motor inrush current without nuisance blowing
• Rejection base prevents installation of a higher-rated fuse, protecting the circuit from overcurrent
• Rated 10,000 AIC for reliable fault interruption on standard residential and light commercial circuits
• Oversized clear window allows visual inspection of fuse element without removing the fuse
• UL listed for use in motor and appliance branch circuits at 125 volts AC
• Sold as a 2-pack for convenient replacement stocking

Compatibility

Designed as an OEM-style replacement for Type S time-delay plug fuse applications in residential and light commercial branch circuits, including air conditioner, furnace blower, pool pump, and deep freezer circuits requiring a 20-amp, 125-volt S-Type fuse.

Installation Notes

S-Type plug fuses are installed and serviced by licensed electricians working under applicable NEC guidelines. Always shut off main or branch circuit power before replacing a fuse. Confirm the load-side circuit is de-energized before handling. Never bypass or substitute a higher-rated fuse in a Type S rejection-base holder.
