REF615E-E-HBFAABAANAA4BNA11E is an advanced relay protection device produced by ABB.The following is a detailed introduction to the device:

1.Main functions

The device is designed for equipment protection and control in power systems and integrates multiple protection functions to ensure the stable operation of power systems.These protection functions include:

Overcurrent protection:When the current exceeds the set value,the device automatically cuts off the circuit to prevent damage caused by equipment overload or short circuit.

Undervoltage protection:When the voltage is lower than the set value,the device will sound an alarm or cut off the circuit to prevent the equipment from being damaged by running under low voltage conditions.

Overvoltage protection:When the voltage exceeds the set value,the device will quickly cut off the circuit to protect the equipment from being damaged by high voltage shocks.

Phase loss protection:When a phase in the power system loses power supply,the device will sound an alarm and may cut off the circuit to prevent the equipment from being damaged due to phase loss operation.

Ground fault protection:When a ground fault occurs at a point in the power system,the device will quickly cut off the fault circuit to prevent the fault from expanding and causing greater losses.

2.Technical Specifications

The technical specifications of the REF615E-E-HBFAABAANAA4BNA11E device are as follows:

Rated voltage:usually 220V(but some descriptions mention the rated voltage as 150V,which may be related to the specific application scenario or product series and needs to be confirmed based on the actual product).
