Overload protector is a typical bimetal overcurrent protector,Using the physical properties of bimetal,Applied to various motor overcurrent protection. The role of overload protection:Commonly used in the installation of the power transmissi....
When the motor is overloaded (greater than the preset current of the protector) or the motor is disconnected (one or more phases without current), the normally closed shock 3 or 4 will be temporarily disconnected (the circuit in the figure).....
What is an overload protector? Overload protectors are often referred to as: Torque Holder, Overload Protector, Torque Clutch, Torque Clutch, Limiter, Axial Load Overload Protector, Torsion Limiter, Safety Clutch, Safety Coupling, Force Limi....
Motor protection is a comprehensive protection for the motor. That is, when the motor has overload, phase loss, stall, short circuit, over voltage, under voltage, leakage, three-phase unbalance, overheating, bearing wear, and eccentricity o....
Working principle and classification of Breaker protector switch. The Breaker protector switch of the air conditioner compressor is generally a jump-type bimetal protector.....
In the late 1980s, in order to adapt to the domestic voltage, the power system was not directly grounded, and the defects of the vacuum switch of the traditional arrester were overcome. A new type of operating overvoltage protection device,....
Compound motor overload protector The working current of a large compressor is very large, and the arcing of the overload protector causes arcing and cannot be used. The commonly used protection method is the protection method of the thermi....
The role of the motor protector is to provide complete protection of the motor. A device that alarms or protects the motor when there is overload, overcurrent, phase loss, stall, short circuit, overvoltage, undervoltage, leakage, three-phas....
Short-circuit protection is a fault in the circuit. For example, the resistance of the wire is almost negligible without passing through the load. Therefore, the huge current generated instantaneously provides a cut-off power supply to preve....
