Power entry connectors have a wide variety of applications in the field of electrical engineering. Connectors are used to connect electrical cables, wires, and other components to create a circuit or system. In this article, we will focus on the FN382B-6-21 power entry connector and discuss its application field and working principle.

The FN382B-6-21 is a 3-pole power entry connector with integrated switching and protection functions. It is designed for surface mount applications such as panel boards, junction boxes, and other circuit-mounting applications. The connector features a built-in 10A switching NO/NC contact on each pole. It also features integrated surge protection against over-voltage and over-current, as well as integrated EMI/RFI filtering. The connector is UL approved and has been tested to UL 60950, which is the safety standard for electrical equipment with or without power supply connection.

The FN382B-6-21 power entry connector is typically used in applications where an integrated switching and/or protection function is required. For example, it could be used in a circuit breaker switch, a surge protection device, or a panel board application where a switch is necessary. Additionally, it can be used to provide protection against EMI/RFI noise. The integrated 10A/9A switching contact allows the connector to be used as a single pole switch, which can be used to control power or signal in panels and junction boxes.

The working principle of the FN382B-6-21 power entry connector is simple. When power is applied to the connector, it provides an electrical path between the two connection points. This path can be used to switch and protect the power circuit. The integrated switching contact can be used to switch power or signal from one connection point to another. The integrated surge protection circuitry protects the power circuit from overvoltage and overcurrent conditions. The integrated EMI/RFI filter blocks any interference generated by the power circuit, preventing false signals and interference.

In conclusion, the FN382B-6-21 power entry connector is a versatile and reliable means of connecting electrical components. Its integrated switching and protection features make it ideal for a large range of applications, from panel boards to junction boxes and circuit surge protection devices. Its simple working principle and UL approval makes it a safe and dependable choice for any electrical component.
