Terminal Blocks – Barrier Blocks

Barrier blocks and terminal blocks are fundamental components in a broad range of applications, from distributed control systems and power distribution systems to the automation of vehicles, ships, and aircraft. They enable the connection of two-way circuits as well as controlling their current flow.

The 1514-ST barrier block is a type and style of terminal block which interconnects multiple circuits. It features a barrier strip design with mateable end-stops and contacts spaced 5mm apart. It is available in several current and voltage ratings, including 10A/250V and 30A/600V. The 1514-ST also features a standard pitch of 5mm for mounting in a variety of applications.

Working Principle

The 1514-ST works by providing reliable connections between two or more wires or circuits. It functions as an insulated barrier which effectively prevents the electrical current and voltage from passing through the block and into the wires. This makes it suitable for a variety of applications, including commercial, residential, and industrial applications. The 1514-ST is designed to meet UL and IEC standards for typical industrial applications.

The terminal block consists of a series of metal pieces that are connected together with insulated material. The insulated material provides an electrical barrier between terminals, thus protecting personnel from electrical hazards. The metal pieces fit into slots that are created in the base of the terminal block. The contacts are connected to the conductive metal pieces via soldering, and these connections are further secured by using a special “barrier” washer. This washer prevents the contacts from becoming disconnected due to vibration or strain.

The barrier block is designed for easy installation and maintenance. The insulated metal pieces are pre-drilled and tapped for securing the pieces together with up to four 16mm screws. The insulated pieces are also pre-formed with slots and cuts to allow the insertion of the wires. The terminals feature clearly labeled NO (normally open) and NC (normally closed) contacts, and the terminals are available in various colors for easy circuit identification. The terminals have a standard pitch of 5mm, so they can be easily mounted in a variety of applications.

Application Field

The 1514-ST barrier block is suitable for a wide range of applications, including power distribution, control panels, and motor drives. In vehicles, ships, and aircraft, it can be used to provide a reliable connection between two circuits. In industrial automation applications, it can be applied for controlling power to a variety of loads including motors and solenoids. And in offices, the terminal block can be used for connecting LEDs, printers, and other electrical equipment to their power sources. It is also extensively used in residential applications, allowing the automation of whole-house systems for temperature and lighting.

The terminal block is a versatile and efficient device that has been designed to meet UL and IEC standards for greater safety. It enables reliable connections between two or more circuits, helping to ensure the safe transfer of electrical power. The 1514-ST terminal block is the perfect choice for a variety of industrial, automotive, and residential applications, providing reliable connections in a cost-effective and efficient way.
