Cooper Bussmann BP/S-20 Type S Plug Fuse 20A 2 Pack

Product Description

The COOPER BUSSMANN BP/S-20 is a Type S plug fuse rated at 20 amps with a time-delay (Fusetron) design. It is used to protect branch circuits in residential load centers and fuse panels where Type S rejection-base fuses are required. The time-delay characteristic allows motor starting current and brief inrush loads to pass without nuisance opens, while still clearing sustained overloads and short circuits. Each card contains 2 fuses, making it a practical purchase for service calls and panel work. Licensed electricians and HVAC technicians are the primary installers of this fuse type.

Type S plug fuses are used in older residential fuse panels and subpanels that require the tamper-resistant rejection base to prevent overfusing. The BP/S-20 is suited for 20-amp circuits supplying appliances, HVAC equipment, and general branch loads in homes and light commercial buildings. The carded 2-pack format is well-suited for field stock and service van inventory.

Key Features

• 20-amp time-delay rating handles motor inrush without nuisance opens
• Type S rejection base prevents installation of higher-rated fuses in the same socket
• Fusetron time-delay element protects motors and other inductive loads
• Carded 2-pack for easy retail and field stock management
• Compact dimensions: 2.75 inches long x 1.375 inches wide x 0.625 inches high

Compatibility

Designed as an OEM-style replacement for residential and light commercial fuse panels requiring Type S plug fuses with a 20-amp rating and rejection-base socket fitment.

Installation Notes

Type S plug fuses are installed and replaced by licensed electricians in accordance with NEC requirements. Always shut off or disconnect the main service before working inside a fuse panel. Never substitute a higher-amperage fuse for the rated circuit protection. The Type S rejection base is designed to prevent this, but installers should confirm the socket and fuse rating match the circuit conductor size before energizing.
