Introduction

3120-F621-P7T1-W12FY4-10A is a kind of circuit breaker in the electrical industry, it is mainly used to protect the circuit from damage because of overload or short circuit. This circuit breaker features its ability to meet various applications, such as automation, process control, machine tools, commercial buildings and power systems.So, what is the working principle of this 3120-F621-P7T1-W12FY4-10A circuit breaker and what are the application field? In this article, we will discuss the working principle and application fields of the 3120-F621-P7T1-W12FY4-10A circuit breaker.

Working Principle

The working principle of the 3120-F621-P7T1-W12FY4-10A circuit breaker is simple and efficient. When the current in a circuit exceeds the rating, the circuit breaker trips and interrupts the electricity supply by opening up the circuit.Then, the current will no longer flow through the circuit and the power supply will be cut off.The 3120-F621-P7T1-W12FY4-10A circuit breaker uses a bimetallic strip to protect against overload. The bimetallic strip is composed of two metals with different thermal expansion coefficients, when the current passing through the strip exceeds the rated value, it will heat up and bend due to the Joule heating effect, and then drive the mechanical trip system to open the circuit.

Application Fields

The application field of the 3120-F621-P7T1-W12FY4-10A circuit breaker is wide and diverse. It could be used in electric control systems, motors, construction machinery, electronic equipment, electrical installations and electric heating systems. It is suitable for controlling and protecting electric circuits of rated voltage ranging from AC 250V to 500V.In addition to electric power products, 3120-F621-P7T1-W12FY4-10A circuit breaker can also be used in the pneumatic or hydraulic control system to provide air supply or oil pressure supply, enabling a reliable connection between the system and power source, and maintaining a safe and stable operation of the whole system.

Advantages

Compared with other circuit breakers, 3120-F621-P7T1-W12FY4-10A circuit breaker has advantages of reliable operation, long life and high sensitivity.Firstly, it has reliable connection.
