Cooper Bussmann T-30 Type T Plug Fuse 30A 4 Pack

Product Description

The COOPER BUSSMANN T-30 is a 30-amp Type T plug fuse with a time-delay (Fusetron) element, designed for residential and light commercial electrical panels and disconnect boxes. The time-delay characteristic allows harmless motor startup inrush currents to pass without nuisance opening, while still providing reliable overcurrent protection under true fault conditions. Each fuse measures 0.59 inches long by 0.56 inches wide by 0.31 inches high. This listing is sold as a 4-pack, making it a practical choice for service techs stocking commonly replaced fuse sizes.

Type T plug fuses are commonly installed in older residential service panels, air conditioning disconnect boxes, and equipment requiring a standard Edison-base fuse with time-delay protection. The 30-amp rating makes this a frequent replacement in HVAC disconnect applications, electric water heaters, and similar single-phase loads. Licensed electricians and HVAC technicians are the primary installers, though knowledgeable service professionals working within local code requirements also handle these replacements routinely.

Installation Notes

Installation must be performed by a qualified electrician or licensed trade professional in accordance with NEC requirements. Always shut off the main disconnect or branch circuit supplying the fuse holder before removing or installing a fuse. Confirm the replacement fuse amperage matches the circuit rating exactly — never substitute a higher-amp fuse. Inspect the fuse holder for signs of heat damage or corrosion before seating the new fuse.
