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

Product Description

The COOPER BUSSMANN TL-25 is a plug-style, time-delay fuse rated for 25 amps at 125 volts. It is designed to protect residential electrical branch circuits and equipment from overcurrent conditions, providing a delay that prevents nuisance tripping caused by motor startup inrush currents. The fuse body measures 2.25 inches in diameter and is constructed from plastic. With a 10 kA RMS symmetrical interrupting rating, this fuse can safely clear high-fault-current events. Electricians and facilities maintenance technicians install this type of fuse in plug fuse panels and disconnect boxes commonly found in older residential and light commercial wiring systems.

The TL-25 is suited for residential and light commercial applications where plug fuse panels remain in service. Common installations include older-style Edison-base fuse boxes protecting circuits for motors, appliances, and general-purpose loads that experience high startup inrush current. The time-delay characteristic allows temporary overcurrents to pass without opening the fuse, while still protecting against sustained overloads and short circuits. Electricians servicing legacy fuse panel systems will find this fuse a direct fit in standard plug fuse sockets.

Key Features

• 25 amp rating suits branch circuit and appliance circuit protection
• Time-delay design tolerates motor startup inrush without nuisance opening
• 125-volt rating appropriate for standard residential single-phase circuits
• 10 kA RMS symmetrical interrupting capacity handles high-fault-current events
• Plastic plug body measures 2.25 inches in diameter for standard socket fit
• CE Certified and UL Listed (Guide JEF, File E12112) for code-compliant installations

Compatibility

Designed as an OEM-style replacement plug fuse for standard 125-volt plug fuse panels and disconnects accepting 2.25-inch diameter plug fuses.

Installation Notes

Plug fuse replacement should be performed by a qualified electrician in accordance with NFPA 70 (NEC) requirements. Always shut off the main disconnect or de-energize the panel before replacing fuses. Confirm the replacement fuse amperage matches the circuit rating before installation. Never substitute a higher-amperage fuse than the circuit is wired for, as this removes overcurrent protection.
