- Over - current Protection: All exhaust fan control boxes are equipped with over - current protection devices, such as thermal relays or circuit breakers. When the current flowing through the fan motor exceeds the rated value, these devices will automatically cut off the power supply to prevent the motor from overheating and burning out.
- Over - voltage and Under - voltage Protection: They can detect abnormal voltage conditions. If the input voltage is too high (over - voltage) or too low (under - voltage), the control box will take appropriate measures, such as shutting down the fan or sending an alarm signal, to protect the motor and other electrical components.
- Short - circuit Protection: In case of a short - circuit in the electrical circuit, the control box can quickly cut off the power to prevent damage to the equipment and reduce the risk of fire.
- Standardized Design: The control boxes are designed with standardized mounting holes and wiring terminals, making them easy to install in various locations. The wiring is clearly labeled, which simplifies the connection process for electricians.
- Accessible Components: The internal components are arranged in an accessible manner, allowing for easy inspection, repair, and replacement. This reduces the downtime during maintenance and ensures the continuous operation of the exhaust fan.
