Terminal blocks are electrical connectors that allow for the secure yet removable connection of two or more electrical conductors within an industrial or residential application. The 1727803 terminal block is a wire-to-board type that is commonly used for terminating both incoming and outgoing wiring.

Characteristics and Benefits

The 1727803 terminal block typically has a rectangular body style with a width 19.5mm and a height 16mm. It is suitable for a maximum voltage of 300V ac and a maximum working current of 10 A per contact. The terminal block has one contact in the center and two contacts on either side to allow the connection of three different wires. The top of the terminal block contains a self-locking mechanism, ensuring a secure connection until released with the help of a tool.

Suggested Applications

The 1727803 terminal block is commonly used in commercial and residential applications for a variety of purposes. It is well-suited for direct connection of wires and circuits in distribution boxes, control relays, and other related systems. It is also widely used in appliances, lighting systems, switchboards and other electrical devices. The terminal block is UL (Underwriters Laboratories) approved for use in most industrial and commercial settings.

Working Principle

The 1727803 terminal block functions by creating a secure connection between two or more wires through a spring-loaded mechanism. The wires are positioned in the center of the terminal block and the self-locking mechanism is closed shut. The mechanism tightly, but not rigidly, clamps down on the wires, creating a secure, yet temporary connection.

When the connection needs to be broken or released, a special tool called an extraction tool is used. The extraction tool is placed over the spring-loaded mechanism and a small lever is pressed down. This releases the mechanism and allows the wires to be pulled out of the terminal block. This procedure is typically performed using a rotary motion, making sure not to twist or damage the wires being connected.

The 1727803 terminal block is a reliable, convenient, and economical way to connect electrical conduits and circuits. It is extremely useful in all types of electrical applications and is often chosen as a preferred solution. As one of the most popular wire-to-board terminal blocks, the 1727803 is widely used in commercial, residential, and industrial settings.
