Cooper Bussmann BP/SC-20 Type Sc Cartridge Fuse 20A

Product Description

The COOPER BUSSMANN BP/SC-20 is a Type SC cartridge fuse rated at 20 amps and 300 volts, sold in a 2-pack carded format. It features a time-lag (slow-blow) design that tolerates brief inrush currents without nuisance tripping, making it well suited for motor loads and transformer-fed circuits. The compact form factor measures 13/32 inches in diameter and 1.83 inches in length, fitting standard SC-type fuse holders. Licensed electricians and HVAC technicians are the primary installers of this component in low-voltage and line-voltage control circuits.

Type SC cartridge fuses are commonly used in residential and light commercial applications where space-saving, reliable overcurrent protection is required. Typical installations include HVAC control panels, small motor circuits, transformer secondary circuits, and other equipment requiring a compact fuse with time-delay characteristics. The 300V rating covers standard single-phase branch circuit applications in these environments.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with the NEC and applicable local codes. Always de-energize and lock out the circuit before replacing a fuse. Verify that the replacement fuse matches the amperage and voltage rating of the original. Never substitute a higher-rated fuse to bypass a fault condition.
