Sacrificial part
Encyclopedia
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, and thus protect other parts of the system.
Examples of sacrificial part include:
Electric current
Electric current is a flow of electric charge through a medium.This charge is typically carried by moving electrons in a conductor such as wire...
, or other unexpected and dangerous situations. The sacrificial part is engineered to fail first, and thus protect other parts of the system.
Examples of sacrificial part include:
- Electrical fusesFuse (electrical)In electronics and electrical engineering, a fuse is a type of low resistance resistor that acts as a sacrificial device to provide overcurrent protection, of either the load or source circuit...
- Over-pressure burst disks
- Mechanical shear pinsShear pinA shear pin is a safety device designed to shear in the case of a mechanical overload, preventing other, more-expensive parts from being damaged...
