T21-3-3.00A-01-11AL

Introduction:

Circuit breakers, also known as over-current protection devices, are widely used to protect electrical systems and components from damage caused by excessive currents. The T21-3-3.00A-01-11AL is a specific type of circuit breaker designed with a unique set of features to provide optimal protection against over-currents. This article will explain the application and working principle of the T21-3-3.00A-01-11AL circuit breaker.

Applications:

The T21-3-3.00A-01-11AL circuit breaker is suitable for use in low-voltage circuits. It is suitable for use in residential, commercial, and industrial applications. This type of circuit breaker is designed to protect against overloads and short-circuits from both a thermal and arc-fault perspective. This type of breaker is used in low-voltage DC applications, and is particularly well-suited to motor control applications, as it can provide motor isolation even in the presence of short-circuits.

Working Principle:

The T21-3-3.00A-01-11AL circuit breaker uses a combination of thermal and arc-fault protection algorithms to protect against over-currents. When an excessive current passes through the protected circuit, the breaker utilizes a thermal switch and a current transformer to detect the anomaly. The thermal switch can detect an excessive temperature increase, and the current transformer is designed to detect any faults in the current flow. When either of these two mechanisms detects an over-current, the breaker will automatically trip and open the circuit, thus protecting the components from any damage.

In addition to the thermal and current transformer-based protection systems, the T21-3-3.00A-01-11AL circuit breaker also includes a unique arc-fault protection system. This system is designed to detect and interrupt any arcs caused by improper use in the motor circuit. This arc-fault protection system can be helpful to detect any undesired current-to-ground faults in the motor circuit, and will automatically open the circuit to prevent any space or components damage.

Conclusion:

The T21-3-3.00A-01-11AL circuit breaker is designed with a range of features to provide optimal protection from both thermal and arc-fault over-currents. This type of circuit breaker is suitable for a variety of low-voltage applications, including residential, commercial, and industrial use. The combination of thermal and arc-fault protection algorithms make this type of circuit breaker an invaluable tool for protecting sensitive components from over-currents and short-circuits.
