Terminal Blocks - Barrier Blocks are typically used for separating low voltage, instrument and control circuits. The barrier blocks 1776044-3 are designed to provide a simple, economical and safe method of connecting and separating low voltage and instrumentation wiring. They are available in a variety of lengths and ratings and are designed to provide the highest levels of performance.

The 1776044-3 barrier blocks come with a removable interlock knob that locks the device in place. This provides a secure connection and prevents accidental disconnection of the bar. Additionally, the bottom terminal screw is color-coded to indicate the voltage and ampere connection. This aid in troubleshooting and wire identification.

One of the main applications of the barrier blocks is in high-frequency electronic equipment. They are used to provide reliable and safe power and signal transfers between multiple devices. This makes them suitable for connecting components used in communication networks and telecommunication applications. In addition to this, they can be used to connect instruments and control circuits as well.

The 1776044-3 barrier blocks also have a positive locking feature that is unique. The contact points are designed to have small pins engage when the lever is moved, which ensures complete connection between the two devices. The contact points are also mechanically reinforced so as to prevent accidental disconnections. Additionally, these barrier blocks are rated for use up to 50 volts.

The working principle of the 1776044-3 barrier blocks is fairly simple. When the lever of the barrier block is closed, the two devices connected by the barrier block are electrically connected, forming a circuit. The contact points on the barrier block provide the current for the circuit to pass through, and the pins ensure that the circuit is complete. When the lever is opened, the pins and contact points no longer engage, and the circuit is broken.

The barrier block is designed to be simple, economical and safe to use and provides an efficient way of connecting, disconnecting and separating low voltage and instrumentation cables. With its superior interlocking feature, it can be used in high-frequency electronic equipment and communication networks where a secure and safe power and signal transfer is required.
