Terminal blocks are devices used to break electrical circuits or divide them into branches. A terminal block, also known as a terminal board or terminal strip, is a discrete device that enables electrical connections to be made between circuits. These blocks are often used to connect two or more wires together in a single conductor. The C7021-02-1 is a product offered by Mersen that falls into the category of terminal blocks - power distribution.

The C7021-02-1 is a two-level fuse holder block, with a three-pole output connection. This terminal block allows for the use of Class CC or Midget fuses in three-phase systems and is rated up to 600 volts and 100 amps. The C7021-02-1 features a common neutral bar, which allows for the connection of a neutral wire to all three phases. This block is designed for a variety of applications including industrial control panels, machine tools, protective overload relays, power transformers, and welding units. The block is also suitable for use in NEC Class I, Division 1 and NEC Class I, Division 2 hazardous locations.

The C7021-02-1 is a simple yet effective terminal block. Its construction consists of two terminal blocks, which are securely fastened to a base plate. The two terminal blocks are the contact block and the fuse holder block. The contact block is designed with a flat surface so that wires can be connected securely. The fuse holder block is designed to accommodate Class CC or Midget fuses, allowing the current being supplied to a device to be limited. Both of these blocks are held securely in place by two mounting screws.

The working principle of the C7021-02-1 is quite simple. Power is supplied from the fused power supply to the contact block, and is then directed to the fuse holder block. When the fuse holder block is not installed, the power is supplied directly to the device that is being powered. When the fuse holder block is installed, the power is routed through it before reaching the device. This allows the current to be limited, as set by the size of the fuse installed in the fuse holder block.

In summary, the C7021-02-1 is a terminal block designed for power distribution applications. It is rated up to 600 volts and 100 amps, and is suitable for use in hazardous locations. The block is comprised of a common neutral bar and two terminal blocks, and its working principle is based on limiting the current supplied to a device by using a fuse.
