Cooper Bussmann BP/S-30 Type S Plug Fuse 30A 2 Pack

Product Description

The COOPER BUSSMANN BP/S-30 is a Type S time-delay plug fuse rated at 30 amps, sold in a two-pack. Type S fuses are tamper-resistant by design: each amperage rating uses a unique rejection base, preventing the installation of a higher-rated fuse in the same socket. The time-delay (Fusetron) characteristic allows brief motor-start inrush currents to pass without nuisance blowing, while still providing reliable overcurrent protection under sustained fault conditions. Electricians and qualified DIYers install these in residential fuse panels and sub-panels where Type S fuse holders or adapter bases are already in place.

These fuses are used in residential electrical panels for branch-circuit protection of appliances, HVAC equipment, and general-purpose circuits. The 30-amp rating covers loads such as electric dryers, water heaters, and air conditioning circuits commonly found in older residential service panels equipped with Edison-base or Type S fuse blocks. The carded two-pack format is suited for service truck stock or keeping a spare on-site after initial installation.

Key Features

• 30-amp Type S time-delay (Fusetron) design allows motor-start inrush without nuisance opens
• Rejection-base configuration prevents insertion of a higher-amperage fuse into the same socket
• Two fuses per carded package — practical for service stock or spare-on-site use
• Compact form factor: 2.75 inches long x 1.375 inches wide x 0.625 inches tall (packaged)
• Designed for residential fuse panels using Type S fuse holders or adapter bases

Compatibility

Designed as an OEM-style replacement for residential electrical panels and sub-panels equipped with Type S plug-fuse holders or Type S rejection-base adapters rated at 30 amps.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements for overcurrent protection. Always shut off the main breaker or remove the main fuse block to de-energize the panel before replacing fuses. Confirm the replacement fuse amperage matches the circuit rating — do not substitute a higher-amp fuse. The Type S rejection base prevents upsizing, but verify the correct adapter base is seated before installing the fuse.
