Cooper Bussmann BP/S-8 Type S Plug Fuse 8A

Product Description

The COOPER BUSSMANN BP/S-8 is an 8-amp Type S plug fuse with time-delay (Fusetron) characteristics, designed for use in residential and light commercial electrical panels. Type S fuses feature a rejection base that prevents substitution with a higher-amperage fuse, adding a layer of circuit protection that standard plug fuses do not provide. The time-delay design allows brief, harmless inrush currents from motors and other reactive loads to pass without nuisance opening, while still responding quickly to sustained overloads and short circuits. This fuse is sold in a carded pack of 5 units and is a standard stocking item for licensed electricians and HVAC service technicians.

This fuse is suited for installation in Edison-base screw-shell fuseholder sockets equipped with a Type S adapter, which locks the amperage rating into the circuit. Common applications include residential load centers, appliance branch circuits, and motor circuits where a tamper-resistant, time-delay fuse is specified or required by the authority having jurisdiction. The 8-amp rating is frequently used on small motor and appliance circuits in both new construction and service replacement work.

Key Features

• 8-amp time-delay rating handles motor inrush without nuisance opening
• Type S rejection base prevents installation of a higher-rated fuse in the same socket
• Fusetron time-delay design provides overload and short-circuit protection
• Carded pack of 5 fuses for convenient field stocking
• Compatible with standard Type S fuseholder adapters in screw-shell panels

Compatibility

Designed for use with Type S fuseholder adapters in standard residential and light commercial screw-shell fuse panels where an 8-amp time-delay plug fuse is required.

Installation Notes

Installation must be performed by a qualified, licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and lock out the panel before removing or installing any fuse. Verify that the correct Type S adapter for the 8-amp rating is installed in the fuseholder before inserting this fuse. Do not bypass the rejection adapter or attempt to fit this fuse into a non-Type S socket.
