A microwave fuse like the BP/ABC series (10A) is a ceramic cartridge fuse designed to protect the microwave from electrical overload. When current exceeds the rated amperage, the internal element melts and cuts power instantly to prevent damage or fire.

These are typically high-voltage, time-delay (slow-blow) fuses, because microwaves draw a surge of current when starting.

• Rated 10 amps (must match your microwave spec exactly)
• Usually ceramic body (handles higher heat and voltage than glass)
• Often slow-blow (time delay) for appliance startup loads
