T38521-21-0 Datasheet/PDFT38521-21-0 is a type of terminal block commonly used to connect electrical pumps, fans and other control devices. It is often found on the electrical panels in industrial and commercial settings. It is made up of two pieces: the terminal block bridge and the barrier block.
Terminal Block Bridge
The terminal block bridge is the main linkage between the control device and the power supply, and it is made up of two insulated copper pieces fitted together. One piece contains the terminals for the power supply while the other side contains the two terminals for the control device. The copper pieces can be soldered or screwed together to make an electrical connection.
Barrier Block
The barrier block is an additional safety device that prevents electrical currents from jumping between the two pieces of the terminal block bridge. It is typically a rectangular piece of plastic with a hole in the center and a series of small metal pins on the side. The barrier block slides onto the bridge and prevents the two pieces from coming into contact with each other. The pins in the barrier block grab onto the bridge and ensure that the connection is secure.
Working Principle
The working principle of T38521-21-0 is relatively straightforward. When power is applied to the terminals of the bridge, electricity flows from the power supply to the control device. The barrier block prevents electricity from jumping or sparking between the two pieces. This helps to ensure that the power supply is completely isolated from the control device.
Application Field
T38521-21-0 is used in a variety of industrial and commercial applications. It is commonly found in control panels, but it is also used in other electrical systems such as pumps, fans and other motorized equipment. In addition, it is often used to connect control devices in hazardous areas, as the barrier block helps to reduce the risk of sparking.
Conclusion
The T38521-21-0 terminal block is an efficient way to connect control devices to a power supply. The combination of the terminal block bridge and the barrier block helps to ensure a safe, secure connection. It is widely used in a variety of industrial and commercial applications, and it is an invaluable part of many electrical systems.
