Terminal Blocks - Barrier Blocks

T37022-26-0 is a type of terminal block that is designed to provide secure electrical connections in a wide array of industrial and avionic applications. Barrier blocks also provide improved safety to personnel by providing an insulation barrier between conductive parts of a circuit. They are primarily used to terminate and connect multiple wires/cables to an electrical load or contact, allowing for easy maintenance or troubleshooting.

Application Field

T37022-26-0 barrier blocks are most commonly used in the industrial, automotive, aerospace & defense, and medical industries. These blocks can accommodate a wide range of different wire sizes, including up to two AWG 18-14 stranded and two AWG 22-16 solid wires. The compact design of the block also helps to make it ideal for high vibration environments.

Working Principle

T37022-26-0 barrier blocks work by providing an insulation barrier between two conductors and provide secure electrical connections. The insulation barrier between the conductors prevents the flow of electrical energy between them, meaning that any current leakage is blocked and safe. The terminal block is connected with an industrial grade UL 94V-2 rated material, making it suitable for use in harsher environment. It also features an integral latch, which allows for easy connection and disconnection of wires. The terminal block also features stainless steel screws with a torque limiting feature, meaning it is able to withstand high torque applications, such as in the automotive and aerospace industries. The barrier block also features an earthing and strain relief feature which helps to improve the reliability of the connection and prevents potential loosening of the terminal block due to vibration or movement. The terminal block is RoHS compliant and is UL recognized for up to 150 volts.

Conclusion

T37022-26-0 barrier blocks provide secure electrical connections and improved safety to personnel in a wide variety of applications. The terminal block is able to accommodate various wire sizes and features a UL 94V-2 rated material with integral latch that allows for easy connection and disconnection of wires. Additionally, the terminal block features a stainless steel screw with torque limiting feature, earthing and strain relief, and is UL recognized for up to 150 volts.
