Power entry connectors are essential components when it comes to distributing electrical power. In this article, we look at the application field and working principle of the FN389-2-21 power entry connector, an inlet suitable for a variety of applications.

FN389-2-21 is a universally approved inlet suitable for use in connecting power from mains supply to electrical equipment with a rated voltage of up to 250V and currents of up to 10A. This connector is a perfect match for audio and visual equipment, home appliances, computers, testing instruments, and lighting systems; just to name a few applications.

The FN389-2-21 is designed with a series of safety features that protect the equipment connected to it. A fuse acts as the main protection against a short circuit and is accompanied by a pair of thermistors which can detect and respond to any excessive heat. This and other protective systems ensure that the user (or their equipment) does not receive any form of electric shock.

The FN389-2-21 connector features a switch that can be used to disable power supply to the connected equipment, in addition to a “Test” button which can be used to test the system\'s proper functioning. Furthermore, the FN389-2-21 is wrapped in a durable insulating material, which also increases its resistance to mechanical shock.

Internally, the FN389-2-21 houses a set of terminals which are used to transfer electricity from the mains supply into the connected equipment. The terminals of this power entry connector are made from premium quality copper, and are designed to keep electrical resistance at a minimum. In addition, the internal terminal layout allows the user to easily connect any number of electrical wires to it.

The FN389-2-21 inlet also features an insulation and contact system which ensures that the connected equipment is properly isolated. The connector comes with two different pins – one for the neutral terminal and one for the live terminal. This helps to ensure that the correct and safe electrical circuit is created and that no short circuits occur.

The FN389-2-21 power entry connector is thus a perfect match for a variety of applications and devices. It has a range of safety features, a durable insulation system, and low electrical resistance terminals, and it is easy to install. Therefore, it is a great choice for any project that requires reliable and efficient power transfer and supply.
