Cooper Bussmann T-25 Plug Time Delay Fuse 25A 125V

Product Description

The COOPER BUSSMANN T-25 is a plug-style time delay fuse rated at 25 amps and 125 volts, designed for use in residential and light commercial electrical systems. With a 2.25-inch overall diameter and a dual-element construction, it provides reliable overload and short-circuit protection. The time delay characteristic allows temporary inrush currents from motors and compressors to pass without nuisance tripping while still responding quickly to sustained overcurrent conditions. It mounts directly into a standard Edison-base fuse holder. Electricians and HVAC technicians install this fuse as a protective device in circuits requiring a UL Listed, CE-compliant overcurrent element.

The T-25 is suited for residential fuse panels, sub-panels, and equipment disconnect boxes where an Edison-base plug fuse is specified. It is commonly used to protect branch circuits serving motors, HVAC compressors, appliances, and similar loads that draw high startup currents. The dual-element design distinguishes it from standard fast-blow plug fuses, making it the appropriate choice where temporary inrush current must be tolerated without sacrificing fault protection. The plastic body construction keeps it lightweight and compatible with standard Edison-base fuse holders.

Key Features

• Time delay dual-element design tolerates motor and compressor inrush currents without nuisance tripping
• 25-amp rating with 125-volt maximum voltage
• 10 kA RMS symmetrical interrupting capacity for robust short-circuit protection
• 2.25-inch overall diameter fits standard Edison-base fuse holders
• Plastic fuse body construction for lightweight, insulated performance
• UL Listed (Guide JEF, File E12112) and CE 248-11 certified

Compatibility

Designed as a direct-fit replacement for standard Edison-base plug fuse holders accepting a 2.25-inch diameter time delay fuse at 25 amps and 125 volts.

Installation Notes

Installation must be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and verify zero voltage at the fuse holder before removing or installing the fuse. Do not exceed the fuse holder or circuit voltage and amperage ratings. Never substitute a higher-rated fuse in place of the specified protective device.
