Circuit breakers are an essential component of modern electrical systems, providing protection for the operation of electrical components, devices and networks. The 3131-AF1PT-000000-1T3-20A is one such device, designed to protect electrical equipment from overcurrent and shorting. Below we will explore the application field and working principle of this circuit breaker.

Application Field

The 3131-AF1PT-000000-1T3-20A is designed for use as a control system power-circuit interrupting device. It is suitable for use in applications where current ratings of 50 - 3,000A or a voltage rating of 750VAC or 1,000VDC are required. It is also capable of using 208/480VAC or 240/415VAC controllers, and can support both single and three-phase power applications. Additionally, this model features an integrated, adjustable trip setting mechanism, which allows for easy customization of the required level of current protection.

The 3131-AF1PT-000000-1T3-20A is designed for use in a wide range of commercial and industrial applications, from small machinery and HVAC systems to high-power equipment like substations, transmission lines and factories. Due to its adjustable trip setting and high current capacity, this circuit breaker is particularly well-suited for use in environments with fluctuating current requirements. This makes it an excellent choice for both new installation and replacement of existing circuit breakers.

Working Principle

When an overcurrent or short-circuit occurs, the 3131-AF1PT-000000-1T3-20A will ensure that the flow of energy is stopped by securely opening the circuit. This is achieved through the device\'s two separate components. The first is an adjustable trip-coil, which is designed to sense any fluctuation in the current and cause an electrical signal to be triggered when the set threshold is exceeded. The second component is an electromechanical trip unit, which immediately stops the flow of current through the circuit as soon as the electrical signal is received.

In order to reset the circuit breaker, the trip-coil must first be reset to its default position. This is normally achieved by manually cycling the 3131-AF1PT-000000-1T3-20A\'s reset switch. Once the trip-coil is reset, the reset switch must then be released and the circuit breaker is ready to be used again. This process ensures that the circuit breaker is kept in a safe and reliable state, while also providing the flexibility to change the trip-coil settings if necessary.

The 3131-AF1PT-000000-1T3-20A circuit breaker is an efficient, reliable and cost-effective solution for protecting a wide range of electrical systems. Its adjustable trip-coil setting and high current capacity make it an ideal choice for applications that experience fluctuating current requirements, while its electromechanical trip unit ensures that the flow of electricity is quickly and securely shut off in the event of an overcurrent or short-circuit.
