T37021-11-0

The T37021-11-0 Terminal Block, which is part of the barrier type of terminal blocks, is suitable for various electrical connection applications in various electrical and electronics systems. It is also commonly referred to as a test point terminal block.

This type of terminal block features a special two-piece friction locking construction. The two pieces can be easily separated and joined back together without the need for any tools. It also has a cam-type mechanism that helps lock them into place once they are joined. It is available in various sizes and gives a secure connection for either a full or partial cross section.

In addition, it is UL 94V-0 rated, which means that it is flame-retardant and designed to prevent the spread of fire. It also has a moisture clearance rate of 2 x IP20, making it suitable for use in a damp environment.

The T37021-11-0 terminal block can be used in various applications, including for high voltage, low voltage, electrical supply, test and instrumentation systems, and mechanical relay systems. It is also suitable for use in different industrial systems such as automation, control systems, ventilation systems, and power systems.

Working Principle

The main working principle of the T37021-11-0 terminal block is based on the contact pressure between the two pieces that make up the terminal block. This pressure ensures good electrical contact between the conductors and terminals of the connector.

The contact pressure is achieved by the use of the cam mechanism on the two pieces. The force generated by the cam locks the parts together, providing a secure and reliable connection. The contact pressure also ensures that the resistance between the connectors is kept to a minimum, thereby preventing any voltage drop or interference.

The T37021-11-0 terminal block is also designed to provide protection from accidental disconnection and is able to withstand various levels of vibration. It also has an inner sleeve that serves as a conductor when the block is connected, and protects against accidental contact with the contacts, thus providing additional safety.

Conclusion

The T37021-11-0 terminal block is designed for use in various electrical and electronic systems. It is designed to be friction-locked for a secure and reliable connection. The contact pressure ensures good electrical contact, and the inner sleeve provides protection from accidental contact and vibration. It is also UL 94V-0 rated and is suitable for use in damp environments.
