Roller Chain Breakage Protection for Conveyors
Case Number 405
last update: March 7, 2011
When the motor locks up, its rotational torque may break the roller chain. To prevent that from happening, the relay must trip the instant it detects a motor lock error. A thermal relay cannot be used for chain protection because it takes too long to start operating.
Benefit / Efficiency
The K8AB-AS offers effective roller chain protection because it starts operating in 0.1 s or less.
