Introduction

FCA-125-15 is a power relay that has an operating current of over 2 amps. It is commonly referred to as a “heavy-duty” relay due to its ability to conduct a large amount of current. This type of relay is used in industrial applications to control motors, thermostats, circuits, and other applications that require control of large amounts of power. This article will discuss the application field and working principle of the FCA-125-15.

Application Field

The FCA-125-15 is a heavy-duty power relay that is used in industrial applications. It is frequently used to switch power for motors and drives, lighting controls, sensors, and other devices. The relay is also used for controlling the heating and cooling systems in industrial facilities. The relay is extremely reliable and provides high switching performance in applications where frequent switching is required.

The FCA-125-15 also has the ability to control all types of AC voltage and current. This makes it suitable for applications that require the control of alternating current. The relay is also able to switch loads that require up to 1500 amps of current, making it suitable for a variety of industrial applications. In addition, the relay is able to withstand temperatures of up to 85°C, making it appropriate for a variety of environmental conditions.

Working Principle

The FCA-125-15 is a 3-phase power relay with a built-in thyristor for controlling voltage and current. The relay uses a contactor which is a mechanical switch that controls current. The contactor is triggered by an actuating coil, which in turn is energized by a control circuit. The control circuit can be either manual or automatic, depending on the type of application. When the control circuit is triggered, the actuating coil energizes, causing the contactor to close, connecting the power to the load.

The thyristor is triggered when the voltage reaches a certain level in order to prevent overloading of the system. When the thyristor is triggered, it will connect the power to the load and the current will flow, powering the load. The thyristor will remain closed until the current reaches a certain level or the voltage drops. When the current reaches the preset level, the thyristor will open, disconnecting the power.

The FCA-125-15 is a reliable and durable power relay, making it ideal for industrial applications that require frequent switching. The relay has a long life cycle and is designed for high performance, making it a popular choice for a wide range of industrial applications. In addition, the relay is designed to withstand a wide range of temperatures, ensuring that it can be used in a variety of different environments.
