Terminal blocks are an integral component of electrical wiring systems. Consisting of a base, several strands of electrical conductor, and a terminal connector, terminal blocks allow multiple electrical circuits to be easily connected together, making the whole system simpler to maintain. Barrier blocks—also known as ‘breaking’ blocks—are a particular type of terminal block. They are used to connect two or more wires in a safe and secure manner. In this article, we will discuss the 2017-3/4ST application field and working principle.

What are 2017-3/4ST Barrier Blocks

2017-3/4ST barrier blocks are small, compact terminal blocks designed for use in confined spaces and tight quarters. They feature corrosion-resistant bodies made of proprietary impact-resistant nylon and stainless steel, and are rated for a maximum current of 12 amperes. They are designed to be easily installed and are capable of carrying multiple circuits. 2017-3/4ST barrier blocks come with three or four terminal connectors, depending on the type of application.

Typical Applications

2017-3/4ST barrier blocks are commonly used in a variety of applications, ranging from automotive and industrial to commercial and residential. They can be used to safely connect two or more electrical circuits in a variety of situations, including wiring distribution boxes, connecting relay contacts, and providing protection in hazardous or wet locations. They are also commonly used in control and communication systems, as well as for emergency/light duty shunting.

Working Principle

The working principle of 2017-3/4ST barrier blocks is relatively simple. The main body of the terminal block consists of two halves, each containing three or four terminal connectors. The contact terminals are then connected to the electrical circuit via a set of conductive strands. When the terminal block is in the ‘open’ position, the strands and contacts are securely separated by the barrier material. This provides extra insulation and prevents accidental contact between the strands and contacts. To activate the circuit, simply move the terminal block to the closed position, which firmly clamps the contacts together and allows for the flow of electric current.

Summary

2017-3/4ST barrier blocks are small, compact terminal blocks designed for use in confined spaces. They feature corrosion-resistant bodies and are capable of carrying multiple circuits. 2017-3/4ST barrier blocks are commonly used in a variety of applications, ranging from automotive and industrial to commercial and residential. The working principle of 2017-3/4ST barrier blocks is relatively simple—the contacts are separated by the barrier material in the open position and clamped together in the closed position, allowing for the flow of electric current.
