1300840370

The 1300840370 is an enclosed type electromagnetic starter that is suitable for both direct-on-line start and soft start. It features numerous advantages, such as a high starting torque, a wide adjustment range, and multiple protection levels. This starter is widely used in a range of industrial power control applications. In this article, we will discuss the 1300840370 application field and its working principle.

1300840370 Application Field

The 1300840370 is mainly used for the power control of 3-phase AC asynchronous motors. It is suitable for direct-on-line start and soft start application in frequently started equipments, such as compressors, pumps, mixers, and conveyors. This starter can be used to protect machines from overload, short-circuit, and other faults. It is also suitable for controlling motors with a large starting torque.

Working Principle of 1300840370

The 1300840370 works with the use of a magnetic field. The starter is composed of several main parts, including an enclosed contactor, a pilot contactor, four overload relays, and an auxiliary contactor. When the motor needs to start, the starter\'s contactor allows the electric current to pass through and then the auxiliary contactor closes the feedback loop. The overload relays are also connected in the loop to protect the contactor once the starting current exceeds the pre-set limit. After the motor starts successfully, the pilot contactor disconnects the starter from the circuit and the motor runs normally.

Advantages of 1300840370

The main advantages of the 1300840370 starter include:

• Small size: The 1300840370 is much smaller than traditional starters, making it ideal for cramped spaces.
• High starting torque: The starter has a higher starting torque compared to conventional starters, allowing it to be used with motors that need a large amount of torque.
• Wide adjustment range: The starter has a wide adjustment range, which allows users to adjust the starting torque of the motor.
• Multiple protection levels: The starter has multiple protection levels, including overload protection, short-circuit protection, and phase loss protection.

Conclusion

The 1300840370 is an enclosed type electromagnetic starter that is suitable for both direct-on-line start and soft start applications. It features a high starting torque, a wide adjustment range, and multiple protection levels. This starter is widely used for power control applications of 3-phase AC asynchronous motors, such as compressors, pumps, mixers, and conveyors. It is also suitable for controlling motors with a large starting torque.
