Power entry connectors that incorporate an inlet, an outlet and modules offer a great deal of flexibility for a variety of applications. The 3EAH1 series from C&K offers several possible configurations of these connectors, and understanding the principles on which they work can help in selecting the right product.

Inlets

The 3EAH1 series inlets are designed to connect to a standard CEE 7/17 plug, known in the industry as ‘Europlug’. The inlets have 4 contacts, providing a rated voltage of 250V~ and current ratings up to 6A. They are available with either fixed or safety shuttered configuration, with the shuttering mechanism meeting the requirements of the EN 1088 standard. The shuttering mechanism is designed to cut off electricity on insertion of the plug, and open or close depending on the state of the latch.

Outlets

The 3EAH1 series outlets feature 4 contacts that are rated at 250V~ and can carry a maximum current of 6A. They are designed for the same measurement as the inlets, and feature a novel device which automatically disconnects the power in case of a fuse failure. This is linked to a safety shuttering mechanism that is also compliant with EN 1088.

Modules

The 3EAH1 series incorporates several modules for connecting both the inlets and the outlets. These modules are made of UL94V-0 rated materials, and are ideal for applications where space is limited. They offer a great degree of customization, with the options of either single or dual modules, as well as some models with built-in LED indicators to indicate the status of the connection.

Application Fields and Working Principle

The 3EAH1 series is a versatile product, suitable for a variety of applications. It is commonly used in domestic, commercial and industrial settings, such as in computer workstations, medical equipment, professional audio and video equipment, and industrial machines. It is also ideal for mobile equipment and for use in campsites, boats, caravans and motorhomes.

The working principle of the 3EAH1 series connectors is simple. When the plug is inserted, the shuttering mechanism is triggered and electricity is made available to the device. If the plug is removed, the shuttering mechanism is designed to cut off the electricity, increasing safety. In addition, the fuse in the connector will trip automatically if there is a voltage or current surge, preventing damage or risk of fire.

The 3EAH1 series is an excellent choice for a variety of applications, offering a safe and reliable connection. It is a cost-effective solution, and its modular design provides a level of customization that can easily be adapted to different requirements.
