The Protective Relay CSC 237A is applicable to various types of neutral point non direct grounding systems of 10kV and below. It serves as a breakdown protection for large and medium-sized asynchronous motors due to phase faults, overload, and locked rotor. It can be assembled on site in switchgear.

 

 

Quick break protection for phase to phase faults

Overcurrent protection for reactive stall rotor

Overload protection (can choose to trip or only send alarms)

Long start protection

Overheat protection

Disqualification protection (phase loss and phase reversal, negative sequence overcurrent protection, can choose between quasi time limit or inverse time limit)

Grounding protection (zero sequence overcurrent protection, can choose to trip or only send alarms)

Low voltage protection

F-C overcurrent blocking

Non battery protection
