Terminal Blocks - Barrier Blocks

432201-22-0 is a renowned terminal block among the market of barrier blocks that enjoy a wide range of application. They are designed to provide secure, reliable connection of insulated conductors and are widely used in control, instrumentation and lighting applications. On top of providing reliable connection, these barrier blocks can also help with installation, organization, and maintenance of control wiring.

Application Field

The 432201-22-0 barrier blocks are used to connect multiple devices with cables. They offer a variety of options for tight packing and tight installation. With its very low-profile design, these blocks consume less space in the enclosure or control panel. Furthermore, they are available in different sizes, that are suitable for use in control cabinets, machine tools, and industrial automation systems.

Aside from the low-profile design, 432201-22-0 also has high current capacity. Its current carrying capacity is up to 22A for copper conductors and 32A for aluminum conductors. This make it an ideal choice for control and power applications in energy-related industry. Furthermore, they also have high vibration resistance, allowing them to be used in moving machinery and in a wide temperature range from -40°C to +105°C.

Working Principle

The 432201-22-0 Barrier Blocks are based on busbar technology, which provides a very high current carrying capacity for the design and isolates the individual wires on the barrier block from each other. It consists of a pair of power rails on either side, which are divided into several segments and connected using cross-junction terminals. The wiring terminals are attached to the barrier blocks, and the control wires are connected to the busbars using screw-on or spring-cage connections so that their polarity can be identified.

The 432201-22-0 Barrier Blocks can switch up to ten times the rated current as long as the current does not peak. This feature allows them to be used in a variety of applications where a high peak current is needed. Furthermore, these terminal blocks can be tapped in the middle (double entry) or offset to the side (single entry). This flexibility makes them ideal for numerous control cabinet solutions in the field of energy-related industry.
