Barrier blocks are a type of terminal block which are commonly used in electrical controls and industrial plant automation systems. These terminal blocks are designed to act as a physical barrier to protect people and property from excessive electrical current and to protect sensitive components from radio frequency interference (RFI) and electromagnetic interference (EMI). The most common barrier block types are called PLU3-BK and they are widely used in industrial settings for power and communication structures.

The PLU3-BK type barrier block has multiple layers which provide additional insulation and protection from electrical current and electromagnetic interference. The first layer is a center conductor which is typically insulated with rubber or plastic. This is used to carry current and connect to a power source. The second and third layers are typically made of insulating material such as ceramics or polymers. These layers act as a barrier to protect people and property from electric shock and/or interference from radio signals.

The fourth layer consists of a terminal contact which is made from a metal such as copper or bronze. The terminal contact is the part that connects with the power source and provides a physical connection to the wire. This type of barrier block is typically used in industrial applications to separate two circuits or systems electrically while allowing one circuit to be powered from the other.

The working principles of the PLU3-BK barrier block involve the layers of insulation providing electrical and interference protection. The center conductor is used to carry current and provide a physical connection to the power source. The insulating layers act as a barrier to protect people and property from electric shock or external interference. The terminal contact is the connection point to the power source and allows for the current to pass through the barrier block and to be used in the circuit.

The PLU3-BK is a type of barrier block which can be used in a variety of applications ranging from motor control systems, HVAC systems, and lighting control systems to industrial automation systems. This type of barrier block is commonly used to provide a physical barrier between two circuits or systems while allowing one circuit to be powered by the other. The layers of insulation protect people and property from electrical shock and external interference from radio signals.

For industrial applications, the PLU3-BK design is often used with a push-in type connector which allows for simple and convenient connections. The barrier blocks can also be used in applications requiring portability as they are relatively lightweight and easy to install. The barrier blocks provide electrical insulation and protection in a variety of industrial settings including motor control systems, HVAC systems, and lighting control systems.
