Terminal Blocks - Headers, Plugs, and Sockets -282816-3 Application Field and Working Principle

Terminal Blocks, Headers, Plugs, and Sockets are a wide range of electrical components used to establish connections between two or more circuits. The 282816-3 is a special type of terminal block which is particularly designed for applications demanding high current and extreme durability. This type of terminal block consists of two parts: the contact block and the ground/mounting block.

The Contact Block

The contact block is composed of the following components: a screw terminal which accepts wires of up to 8 mm in diameter, a pressure screw contact which accepts wire of up to 10 mm in diameter and its surface is designed for higher current, copper-zinc alloy contacts and stainless steel screws. The contact block also includes a tripolar shield for increasing current-carrying capacity and a T clamp for grounding to the mounting board.

The Ground/Mounting Block

The ground/mounting block is a zinc die cast body that ensures electrical continuity between the contact block and the metal mounting surface. This block ensures strength and durability while allowing wiring to be easily secured. The 282816-3 terminal block is designed in such a way that the contact block and the ground/mounting block can be securely and easily mounted without additional nuts and bolts.

Application Field

The 282816-3 terminal block is designed for applications including switchboards, lighting systems, automation systems, and industrial electronics. It is especially favorable in applications demanding high current, for example in heating as well as in electro-chemical processes. It is also suitable for other demanding tasks like transformer and inverter connections.

Working Principle

The 282816-3 terminal block works by setting up a connection between the wire and the contact block through the pressure screw contact and then grounding it to the surface of the mounting board with the T clamp. The high tension screws provide the necessary pressure for establishing a reliable and strong connection, ensuring the continuity of the circuit and avoiding the risk of any failure and unexpected breakdown.

Conclusion

The 282816-3 terminal block is one of the best choices when it comes to wiring and connection systems for high current applications. Thanks to its design, this terminal block achieves a reliable and strong connection with the metal surface ensuring high resistance to fatigue and temperature variation. Additionally, its tripolar shield and T clamp provide additional security while it also facilitates assembly and wiring.
