According to the accessories to the circuit breakerit is divided into two types: with accessories and without accessories.Accessories are divided into internal accessories and external accessories: internal accessories includeshunt trip, undervoltage trip, auxiliary contact and alarm contact;

External accessories include operating mechanism by rotating handle and electric operating mechanism

Main Functions and Features

High-performance 32-bit ARM microprocessor is used to carry out signal processing and inteligent control in real time.

LCD Chinese/English display provides friendly HMI and simple operation.

Long delay, short delay and instantaneous three-stage protection, electronic tripping mode is appied, which is independent of supply voltage.

High breaking ability could ensure the reliability of short circuit protection for the line.

In current fault protection, the fault reasons can be stored and reported.

Detailed real-time information of load can be aueried: current, voltage and phase loss.

It integrates comprehensive electrical protection of short circuit, overload, overvoltage and undervoltage, and phase loss.

Built-in communication function: Remote communication, telemetry, remote control and remote adjiustment could be achieved.
