Circuit Breakers: T21-2-3.00A-01-31A-V Application Field and Working Principle

Circuit breakers are an integral part of an electric system, providing protection by automatically shutting off electrical power in the event of an overcurrent or other fault. The T21-2-3.00A-01-31A-V is a circuit breaker specifically designed for industrial applications, providing maximum current protection for machinery and equipment. This article will look at the application field and working principle of the T21-2-3.00A-01-31A-V circuit breaker.

Application Field

The T21-2-3.00A-01-31A-V circuit breaker is designed for use in high current applications up to 250 A. This type of breaker is often used in industrial applications to protect machines, control circuitry, and other related electrical equipment. In addition, these breakers are UL approved, meaning they comply with national and international safety standards.

The T21-2-3.00A-01-31A-V is designed to provide reliable protection against short circuits, overloads, and ground faults. The breaker also has thermal and magnetic tripping elements, making it highly resistant to false tripping. The combination of these features makes it an ideal choice for protecting machines and other high-power electrical equipment.

Working Principle

The T21-2-3.00A-01-31A-V circuit breaker works by automatically switching off power in the event of an abnormal condition. This is accomplished by monitoring the current flowing through the circuit and comparing it to a set of predetermined thresholds. When the current exceeds a given threshold, the breaker trips and shuts off the power.

The breaker uses a thermally actuated trip device in order to provide reliable and rapid protection. The trip device is designed to detect rapid increases in current, such as those caused by short circuits, and shut off the power instantly. This prevents any further damage to the equipment and wiring.

In addition, the T21-2-3.00A-01-31A-V breaker also has a magnetic trip device which is designed to detect gradual increases in current, such as those caused by overloads. When the current reaches a certain threshold, the magnetic device trips the breaker, cutting off the power and preventing damage to the connected equipment.

Conclusion

The T21-2-3.00A-01-31A-V circuit breaker is a reliable and durable high current breaker designed for industrial applications. It features a thermally actuated trip device for rapid protection against short circuits and a magnetic trip for overload protection. The combination of these features makes this breaker an ideal choice for protecting high-power equipment.
