Electromechanical relay / protection / over-current / panel-mount

Overcurrent Trip
This Switch detects over-current and separates the fault section from the system during that the backside protection device is opening the line. Besides, detects the over-current below the rated breaking current and provides time limit to be cooperated with the protection device. OCR Trip, OCGR Trip function that break the switch are provided.
Overcurrent Lock and spring charge TRIP
This Switch restraints the OCR Trip, OCGR Trip function when the fault current is over 800A, cooperates with the protection device and operates the spring charge Trip function when becomes no-voltage. Operates safely without breaking current over rated breaking current.
Cold Load Pickup
Over-current Trip function and spring charge Trip function are restrained during the setting time, to prevent the malfunction by Cold Load Pickup caused by hot line because of backside closing during the closing of switch or dead line status, After switch is once opened and it is closed before exceeding the Outage Time, this function is not operated. If the switch is closed after exceeding the Outage Time this function is operated normally. Besides, if becomes dead line by CB & REC during switch closing and becomes hotline by reclosing of CB&REC before exceeding the Outage Time, this function is not operated.
