Terminal Blocks - Barrier Blocks

The 325203-20-0 is a terminal block, specifically a barrier block. It is an electrical component used to connect two or more conductors in the same circuit. The mechanism allows multiple connections in a small space. They are used in residential, commercial, and industrial wiring applications. The device makes use of removable screw heads to ensure good electrical contact.

This type of terminal block has a barrier-style construction and is divided into two distinct parts, the contact side and the wire side. The contact side has two rows of terminations. The top row has the centers of the terminals exposed to allow the screw heads of the connecting wires to be held in place. The bottom row is connected to the power supply, usually at the terminals of an electric panel or relay panel.

The wire side features openings that are held in place by a removable insert. This ensures a secure connection between the conductors and the connecting wires. Additionally, the terminals of the contact side are insulated from the conductors of the wire side for added safety. In the event of a power surge, the insulation prevents the current from traveling through the terminal block.

The 325203-20-0 terminal block is typically used in control panel applications and industrial motor wiring and is available with multiple contact sizes. The device has excellent current and voltage rating capabilities, and is RoHS compliant. This device works in partnership with other industrial control components to make up a complex wiring system.

In order to connect conductors to the 325203-20-0 terminal block, the user must first attach the correct terminal to the contact side of the block. Then the connecting wires must be inserted into the openings on the wire side and fastened with the removable insert. The connection is then completed with the external screw head that holds the wiring together. Loose or corroded terminals can cause poor conductivity or even shorts. Connecting the wires correctly and securely is crucial for a safe and good electrical connection.

In conclusion, the 325203-20-0 is a terminal block, specifically a barrier block. It is often used in control panel applications and can make a secure electrical connection in a small space. It features a barrier-style construction with insulated terminals, removable screw heads, and removable inserts. This device is rated for excellent current and voltage, and can be used in commercial, residential, and industrial settings. Proper installation is key to the success of this type of terminal block.
