Terminal Blocks - Barrier Blocks

The MA-17 series of industrial barrier blocks is designed to provide several features such as an integrated LED indicator for when the blocks are energized, a universal finger and thumb grip for easy circuit recognition, a “quick connect” design for quick connections and disconnections, a relocatable mounting position for ease of assembly, and a clear protective door for visual inspection of the wiring inside. This type of terminal block is designed for the connection and distribution of both low voltage and high voltage control circuits.

The MA-17 series is constructed with a rugged metal housing and is designed to provide protection to personnel from coming in contact with high voltage inside the enclosure. This also makes it suitable for applications where physical contact with the high voltage is unavoidable. Industrial application fields include automobile, power tools, emergency lighting, traffic control and integrated services systems.

The working principle of the MA-17 series of barrier blocks is simple. The terminal block is composed of two or more columns, each column consisting of several insulated barriers. The barriers are manually mounted to the terminals of each column to create a voltage transfer circuit. Each barrier acts as a switch to control the flow of electricity between the two columns. The barriers are then covered by a clear protective door to ensure protection against accidental contact with the high voltage inside the enclosure. Once the current is connected, the LED indicator will light up indicating the connection.

The MA-17 series of barrier blocks also has adjustable mounting positions for easy installation. To set the barrier blocks in the desired position, the barrier sections are inserted in the grooved sections of the terminal block, keeping the barriers firmly in place. To secure the connection, the doors of the barrier block are fastened using the included screws.

The MA-17 series of barrier blocks are highly suitable for industrial applications that require the distribution of both high and low voltage circuits in an enclosed and safety-oriented environment. Its integrated LED indicator provides an easy way of verifying the success of the wiring connections while its clear protective doors enable visual inspection and prevent accidental contact with the high voltage circuits. All this combined makes the MA-17 series of barrier blocks an ideal choice for any industrial and manufacturing application.
