The built-in undervoltage release (UVR) and the auxiliary contact pack — two auxiliary switches plus a trip alarm switch — mean this breaker can talk to a PLC or safety relay and drop out on a voltage-loss condition. Communication function is onboard, so you can integrate it into a higher-level monitoring scheme without an add-on module. Ground-fault detection uses summation current formation on the L-conductor, which catches leakage without a separate core-balance CT.
