Cooper Bussmann TL-30 Plug Time Delay Fuse 30A 125V

Product Description

The COOPER BUSSMANN TL-30 is a plug-type, time-delay fuse rated at 30 amps and 125 volts, with a 10 kA interrupting capacity (RMS symmetrical). It measures 2.25 inches in diameter and is constructed with a plastic body. The time-delay characteristic allows momentary inrush currents to pass without nuisance tripping, while still providing reliable overcurrent protection during sustained fault conditions. Electricians and HVAC technicians install this fuse in branch circuits, appliance panels, and equipment disconnect boxes where a standard plug fuse form factor is required.

This fuse is suited for residential and light commercial electrical applications where 125-volt, 30-amp plug fuse protection is specified. Common install scenarios include fused disconnect blocks, load centers, and older-style fuse panels that accept the standard plug fuse form. The time-delay rating makes it appropriate for motor loads and other equipment with high startup inrush current.

Key Features

• 30-amp rating with time-delay fusing to accommodate motor inrush without nuisance trips
• 125-volt AC rated for residential and light commercial branch circuits
• 10 kA interrupting capacity (RMS symmetrical) for fault protection
• Standard plug fuse body, 2.25 inches in diameter, fits conventional fuse sockets
• Plastic fuse body construction
• CE Certified and UL Listed (Guide JEF, File E12112)

Compatibility

Designed as a standard-form plug fuse replacement for 125-volt, 30-amp fuse sockets in residential and light commercial load centers and disconnect applications that accept the plug fuse form factor.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC). Always shut off main power and verify circuits are de-energized with a non-contact voltage tester before removing or installing fuses. Confirm the replacement fuse amperage and voltage rating match the circuit requirements exactly. Never substitute a higher-amp fuse than what the circuit is designed to handle.
