Cooper Bussmann TL-20 Plug Time Delay Fuse 20A 125V

Product Description

The COOPER BUSSMANN TL-20 is a plug-style time delay fuse rated for 20 amps at 125 volts. It features a 2.25-inch overall diameter and a plastic fuse body. The time delay characteristic allows the fuse to handle brief inrush currents without nuisance tripping, making it well suited for motor loads and appliance circuits. The TL-20 carries a 10 kA RMS symmetrical interrupting rating, providing a reliable level of fault current protection. Electricians and service technicians install this fuse type in residential and light commercial panels, fuse blocks, and screw-shell fusible equipment where a standard plug fuse form factor is required.

The TL-20 is used in screw-base fuse holders and panelboards that accept standard plug fuse configurations. Typical applications include branch circuits serving motors, refrigeration compressors, air conditioning units, and other loads that produce high inrush current at startup. Its time delay action distinguishes it from fast-acting plug fuses and prevents unnecessary shutdowns during normal equipment start cycles. Licensed electricians and HVAC technicians are the primary installers in both service and new-installation contexts.

Key Features

• Time delay action tolerates motor and compressor inrush current without nuisance tripping
• 20-amp rating for standard branch circuit protection
• 125-volt AC rated for residential and light commercial service
• 10 kA RMS symmetrical interrupting capacity
• 2.25-inch diameter plug body fits standard screw-shell fuse holders
• UL Listed and CE Certified for code-compliant installations

Compatibility

Designed as an OEM-style replacement for standard screw-base plug fuse applications requiring a 20-amp, 125-volt, time delay fuse in a 2.25-inch diameter form factor.

Installation Notes

Installation and replacement must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and lock out the circuit before removing or installing the fuse. Confirm the replacement fuse matches the amperage and voltage rating of the circuit. Never install a fuse with a higher amperage rating than the circuit is designed to carry.
