Electromechanical Contactor in Motor Starter
Electromechanical contactors are used in motor starters to control the flow of electrical power to the motor. They provide inherent protection against under-circuit conditions.
Under-Circuit Protection
Under-circuit conditions occur when the voltage supplied to the motor is lower than the minimum required voltage. This can happen due to various reasons such as a fault in the power supply, damaged wiring, or a faulty motor starter. Under-circuit conditions can cause the motor to stall or not start at all.
Electromechanical contactors provide under-circuit protection by monitoring the voltage supplied to the motor. If the voltage falls below a certain threshold, the contactor will automatically switch off the power supply to the motor. This protects the motor from damage and prevents it from stalling.
Advantages of Electromechanical Contactors
1. Inherent protection against under-circuit conditions.
2. Reliable and durable.
3. Low cost.
4. Easy to install and maintain.
5. Suitable for a wide range of applications.
Conclusion
Electromechanical contactors are an essential component of motor starters as they provide inherent protection against under-circuit conditions. They are reliable, durable, and cost-effective, making them a popular choice for a wide range of applications.
