Cooper Bussmann T-20 Type T Plug Fuse 20A 4 Pack

Product Description

The COOPER BUSSMANN T-20 is a 20-amp Type T time-delay plug fuse designed for residential and light commercial electrical systems. As a Fusetron-style time-delay fuse, it tolerates brief motor startup inrush currents without nuisance blowing, while still providing reliable overcurrent protection for branch circuits and motor loads. The T-20 measures 0.59 inches long by 0.56 inches wide by 0.31 inches high, making it a direct drop-in for standard Edison-base fuse holders. Each purchase includes 4 fuses per pack, providing a practical on-truck or job-site supply for a licensed electrician performing service or replacement work.

The T-20 is used in residential fuse panels, disconnect boxes, and light commercial load centers that accept Type T plug fuses. The time-delay characteristic makes it well suited for circuits feeding motors, HVAC equipment, pumps, and other loads that draw high inrush current on startup. It is a common replacement fuse for service calls where Type T Edison-base fuses are the installed overcurrent device. The 4-pack format suits service technicians and electricians who stock fuses for routine maintenance and panel service work.

Installation Notes

Type T plug fuses are installed and serviced by licensed electricians. Always shut off the main disconnect and verify the circuit is de-energized with a non-contact voltage tester before removing or installing a plug fuse. Do not replace a fuse with a higher amperage rating than the circuit is rated for, as this defeats overcurrent protection. Work performed on panelboards must comply with applicable NEC requirements and local electrical codes.
