The axial fan protective switch is used to detect the fan's running current in real time in order to prevent motor overload and overcurrent damage. Users can choose a memory function, so that in the event of a sudden power loss when starting, the switch will remain activated until power returns.
|Current Cutoff(A)||120%－150% of rated current (protection time of 8s)|
|Waterproofing Grade of Controller||IPX4|
|Working Temperature of Controller(℃)||-20℃ -- +55℃|
|Rated Motor Power||0.37KW, 0.5KW, 0.75KW, 1.1KW|
|Remote Control Distance||15m|
|One Controller Matches One Draught Fan|
The switch is equipped with an intelligent control chip to ensure the fan will automatically enter a detection state after it starts. When the motor operates in an abnormal manner, the power will automatically turn off in order to product the motor. The switch uses an electronic detection for the current instead of a traditional thermocouple, which ensures the phase loss and overcurrent detection are more accurate and the protection rate is faster at a period of 8 seconds. The switch has a beautiful appearance and practical function, with a one button control that is simple and easy to use. It also features remote control operation, which is more convenient for motor equipment management. Operation is safe and easy, with a plastic casing that is waterproof, corrosion resistant, noise resistant and spark resistant. The switch is also equipped with a motor phase loss protection, motor overcurrent protection and motor overload protection.
