A circuit breaker is a device that can be used to selectively break an electric circuit. It is typically found in industrial electrical systems, such as those found in factories and power plants. 3120-F521-P7T1-W02D-2A is an example of one such circuit breaker and is designed to protect circuits from excess currents and voltage. In this article, we will discuss the application field and working principle of 3120-F521-P7T1-W02D-2A.

The application field of 3120-F521-P7T1-W02D-2A circuit breaker is mainly for thermal protection in medium-voltage switchgear. It is suitable for AC 50/60Hz, rated voltage up to 3.6kV, rated current up to 6300A and short-circuit making and breaking capacity up to 40kA.

The working principle of 3120-F521-P7T1-W02D-2A circuit breaker is based on the thermal characteristics of a bimetal strip. When current flows through the bimetal strip, it heats up, causing it to bend and eventually disconnecting the circuit, thus breaking it. The bimetal strip is designed to be sensitive enough to detect small increases in the current flow, thus enabling it to quickly cut off the circuit before the potential damage caused by the overcurrent is too great.

3120-F521-P7T1-W02D-2A circuit breaker has a number of advantages when compared with other types of circuit breakers. Firstly, it is relatively compact and requires only a small space for installation. This makes it suitable for use in cramped conditions such as on a distribution board. Secondly, the thermal-based system is highly accurate and reliable and thus ensures better protection of the circuit from both low and high current overloads. Finally, the bimetal strip is highly reliable and requires minimal maintenance.

In summary, 3120-F521-P7T1-W02D-2A circuit breaker is ideal for thermal protection in medium-voltage switchgear. It is compact and requires minimal installation and maintenance, while offering a highly accurate and reliable thermal-based system. It provides an excellent level of protection from both low and high current overloads.
