Cooper Bussmann S-15 Type S Plug Fuse 15A 4 Pack

Product Description

The COOPER BUSSMANN S-15 is a 15-amp Type S plug fuse designed for use in residential electrical panels and fuse boxes that require a tamper-resistant, time-delay overcurrent protection device. The Type S design incorporates a rejection base that prevents installation of the wrong amperage fuse in a given circuit, a critical safety feature in older residential service panels. The built-in time-delay characteristic allows momentary inrush currents from motors and appliances to pass without nuisance blowing, while still providing reliable protection against sustained overloads and short circuits. Each package contains four fuses.

Type S plug fuses are commonly installed in older residential service panels where Edison-base fuse protection remains in use. This fuse is appropriate for branch circuits rated at 15 amps, including lighting, general-use receptacle, and small-appliance circuits. Licensed electricians and qualified service technicians install these fuses during panel service calls, fuse replacements, or code-compliance upgrades. The non-tamper design ensures that the correct amperage class is maintained over the life of the installation.

Key Features

• 15-amp rated Type S plug fuse with rejection base to prevent wrong-amperage substitution
• Time-delay design accommodates motor and appliance inrush current without nuisance blowing
• Non-tamper Fustat construction maintains amperage integrity in the circuit
• Sold in a 4-pack for convenient stocking on service calls
• Boxed packaging for organized storage and transport

Compatibility

Designed for use in residential fuse panels and fuse holders that accept Type S plug fuses with a rejection-base adapter, providing a tamper-resistant overcurrent protection solution for 15-amp branch circuits.

Installation Notes

Type S plug fuses are installed by licensed electricians or qualified electrical technicians. Always shut off the main breaker or disconnect power to the panel before servicing fuses. Work in accordance with NEC requirements and all applicable local electrical codes. Never install a fuse with an amperage rating higher than the circuit conductor is rated to carry.
