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. |
