Circuit breakers are commonly used to prevent accidents in the electrical industry, by breaking the electrical current when overloaded or short circuit occurs. B21-2-1.00A-8326-001-V circuit breaker is a fairly common product from Siemens, belonging to the Molded Case Circuit Breaker series. It is designed for industrial and commercial applications to circuit protection of applications against overloads and short circuits that require interchangeable trip units.

Applications

B21-2-1.00A-8326-001-V circuit breaker can be used in a variety of applications, such as control systems, motor control, machine tools, pumps and commercial buildings. It is primarily used as a general protection device to protect a circuit against overload and short-circuit conditions. Besides, it can also be used as a starter and motor starter protection device, as well as the protection device for a transformer.

Working Principle

B21-2-1.00A-8326-001-V circuit breaker works by detecting an overload or short-circuit condition and then cutting off the power supply to the circuit quickly, thus preventing it from overheating, overloading or burning. It uses a thermal-magnetic trip unit, which is designed to measure the heat created when an overload or short-circuit current flows, or the magnetic field created by an overload or short-circuit current. Once the thermal-magnetic trip unit has measured an overload or short-circuit current, it will trip the breaker, thus breaking the circuit.

B21-2-1.00A-8326-001-V circuit breaker is equipped with adjustable trip settings, so it can be tuned to respond to the exact trip current that is necessary for the circuit it is protecting. The trip settings can be adjusted with the use of an external device, such as a current clamp meter or an adjustable voltage or current source.

B21-2-1.00A-8326-001-V circuit breaker also features a two pole switching system, allowing for the simultaneous control of two circuits. This feature makes the breaker ideal for use in heavy duty applications, such as commercial and industrial equipment and lighting. Furthermore, the breakers also come with an auxiliary contact, which provides a switch to the circuit when the breaker is activated, allowing the operator to know that the system has been activated.

Conclusion

B21-2-1.00A-8326-001-V circuit breaker is an ideal choice for industrial and commercial applications, where the protection of circuits against overloads and short circuits is essential. With adjustable trip settings and two pole switching system, the breaker can easily be tuned to the exact trip current necessary to protect the circuit, while the auxiliary contact provides a switch to the circuit when the breaker is activated. All in all, B21-2-1.00A-8326-001-V circuit breaker is an excellent choice for providing reliable protection for various electrical circuits.
