Cooper Bussmann T-15 Plug Time Delay Fuse 15A 125V

Product Description

The COOPER BUSSMANN T-15 is a plug-style, time-delay fuse rated at 15 amps and 125 volts with a 10 kA (RMS symmetrical) interrupting capacity. The dual-element design provides time-delay performance, allowing momentary inrush currents to pass without nuisance tripping while still protecting circuits against sustained overloads and short circuits. The fuse body measures 2-1/4 inches in diameter and is constructed of plastic. It mounts in a standard plug fuse holder and is commonly installed by licensed electricians in residential and light commercial electrical panels, fuse boxes, and branch circuit protection applications.

This fuse is suited for residential service panels and light commercial electrical systems that use plug-style fuse holders. The time-delay characteristic makes it appropriate for circuits serving motors, HVAC equipment, and other loads that draw higher inrush current at startup. The dual-element construction distinguishes it from standard fast-blow plug fuses and helps reduce unnecessary service calls caused by nuisance opens on motor-load circuits.

Key Features

• 125-volt AC rated for residential and light commercial use
• 10 kA RMS symmetrical interrupting capacity
• Plug-body style installs directly into standard plug fuse holders
• UL Listed (Guide JEF, File E12112) and CE 248-11 compliant

Compatibility

Designed as an OEM-style replacement plug fuse for residential and light commercial fuse holders accepting standard 2-1/4-inch diameter plug fuses rated up to 125 volts.

Installation Notes

Installation and replacement should be performed by a qualified electrician in accordance with applicable NEC requirements. Always shut off the main disconnect and verify the circuit is de-energized before replacing a plug fuse. Confirm the fuse holder voltage and amperage ratings match the replacement fuse before installing. Do not substitute a higher-amperage fuse to resolve repeated fuse openings — diagnose the underlying overload or fault condition first.
