Main features

No external power supply required for operation: It can operate independently and does not require additional external power supply to support its basic protection functions and other operations.

Adopt microprocessor technology: Accurate monitoring and control of various parameters are achieved through microprocessors, thereby achieving better protection effects.

High precision: It has high precision in monitoring, judging and protecting actions of current and other parameters.

Sensitive response to the actual current value R.M.S: It can respond quickly and accurately to the actual effective value of the current in order to carry out timely protection actions.

Fault cause indication and tripping data recording: When a fault occurs and causes a trip, the fault cause can be indicated and trip-related data recorded to facilitate troubleshooting and analysis.

Each type of trip unit is interchangeable: this feature provides convenience for product maintenance, replacement and upgrade operations.

Remote control operation: The circuit breaker can be operated remotely, such as opening, closing, alarm reset and other operations can be sent to the circuit breaker and protection tripper. However, the closing command can only be executed after a safety check (eg on the trip unit, no diagnostic alarm is active). The protection tripper can also be set remotely through the communication bus.
