In trip solenoids, 'plunger' typically refers to the moving core in linear motion applications, while 'armature' is more general but often used interchangeably. Both perform the same function of converting electromagnetic force to mechanical motion.
Wear can increase friction, reduce response speed, and cause inconsistent trip timing. Regular inspection for surface scoring, corrosion, or material fatigue is essential for maintaining reliable operation.
