Accessories Function Introduction

Circuit breaker accessory mainly has the following functions:

Accessory	Function	Description
Auxiliary Contact	Indication and Control	Linked with ON/OFF mechanism of the main circuit breaker, used for indicating the status (ON/OFF) of the circuit breaker. Can control or interlock related electrical devices when connected to the control circuit of the breaker.
Shunt Trip	Remote Control Tripping	Used for voltage source excitation, can be independent from the voltage of the main circuit. Enables remote disconnection of the circuit, useful for interfacing with fire alarm systems and emergency stop buttons.
Under-Voltage Trip	Protection Against Low Voltage	Automatically trips off the circuit breaker when the terminal voltage drops below a specified range, protecting electrical equipment from damage due to under-voltage.
Shunt Trip + Auxiliary Contact	Combined Functionality	Combines the functionalities of shunt trip and auxiliary contact.
Under-Voltage Trip + Auxiliary Contact	Combined Functionality	Combines the functionalities of under-voltage trip and auxiliary contact.

Complete Functionality: Achieves multiple functions such as auxiliary contact, remote shunt trip, and under-voltage protection through a combination of different components and assembly.
