Sacrificial part

{{short description|Component engineered to fail first to protect the rest of the device}}A sacrificial part is a part of a machine or product that is intentionally engineered to fail under excess mechanical stress, electrical stress, or other unexpected and dangerous situations. The sacrificial part is engineered to fail first, thus breaking the serial connection and protecting other parts of the system downstream.{{Cite web |last=Industrial |first=Cliff |date=2018-01-17 |title=Parts are Designed to Break?
