Cooper Bussmann SC Series 20 Amp Cartridge Fuses (2-Pack)

This Bussmann series BP-SC-20 time-delay fuse is a Class G, general purpose fuse. It is intended to protect low-voltage electrical circuits from power overloads and short circuits. They have a minimum 300 volt rating and are available up to 60 A. All SC fuses are 13/32" in diameter with varying lengths to provide a rejection feature that helps prevent over fusing (installing a 30 amp fuse in a 20 A circuit).Class G fuses are general purpose, current limiting fuses known for their compact size and as an economical solution for overcurrent protection. They are often used in panelboards, disconnects, and to protect HVAC branch circuits.​ For added protection, these class G fuses also have a "size rejection" feature to prevent you from using a fuse with a higher current rating than the circuit protection requires.As a time-delay fuse, it allows for temporary overload conditions without opening (sometimes called blowing a fuse). This is necessary for equipment that regularly experiences short-term power surges, such as when a motor starts up. The time-delay feature allows an inrush current from the motor to start without opening but still protects against sustained overloads and short circuits. This also allows you to reduce the need to replace expired due to normal inrush overloads.

• Current-limiting fuses can handle a maximum load of 480-volt
• Designed to ensure component protection on branch circuit
• Melamine tubes with nickel-plated brass end caps
