Monitoring/Security Relay for Overvoltage, Undervoltage Control

GKM-11 - Single-phase overvoltage and undervoltage relay, TENSE

Product description

The GKM-11 relay is used to protect sensitive equipment against over- and undervoltage in single-phase distribution systems. When the set over- or undervoltage limit is exceeded, the relay opens the output contact and switches off the load, preventing damage to the equipment.
