| Introduction: |
| It is a Pump Protection Relay. It offers protection against overloading, underloading apart from protection against Phase Failure, Phase Unbalance, Phase Sequence Faults & Dry Running Protection. It is best suitable for individual 3 phase Submersible Pump Protection rated upto 80 A. It eliminate conventional bimetal (thermal) overload relay with superior protection level. It is used for Pumps with Current Sensor CTS. It is recommended for effective Motor Protections in Machine Tools, Compressors & Pumps. |
