Circuit Breakers

Circuit breakers are electrical devices that protect an electrical circuit from potential damage from a short circuit, overload, or other dangerous condition. The 440.0032 is a type of circuit breaker that is designed for use in home and industrial applications. This article will discuss the application field and working principle of the 440.0032 circuit breaker.

Application Field

The 440.0032 circuit breaker is suitable for use in residential and commercial applications. It is capable of providing circuit protection for low voltage circuits up to 600V, such as air conditioners, washing machines, refrigerators, dryers, pumps, air compressors, and other appliances. It can also be used in light duty industrial applications, such as electronic equipment, lighting and small power circuits. The 440.0032 breaker is rated to carry up to 10A, and it has a reset time of 2 seconds.

Working Principle

The 440.0032 circuit breaker employs a thermal and magnetic trip system. When an electrical circuit is overloaded or experiences a short circuit, the breaker trips by releasing a metal actuator. This action opens the contacts within the breaker, which immediately disconnects the circuit. The metal actuator is also connected to a bi-metal strip which helps to detect and measure the amount of current flowing through the circuit. When the current flowing through the circuit reaches a certain level (which is determined by the same metal strip), the metal strip heats up, causing the actuator to open the contacts. This is the thermal part of the trip system.

In addition, the 440.0032 circuit breaker is equipped with a magnetic trip system. When an extremely high amount of current (often referred to as inrush current) flows through the circuit, a large amount of magnetic flux is generated which in turn causes the breaker contacts to open. This is the magnetic part of the trip system and it helps to protect the circuit from further damage or hazards due to extremely high current.

The 440.0032 circuit breaker is designed to provide reliable circuit protection in residential and commercial applications. It employs a thermal and magnetic trip system which helps to protect against overloading, short circuits, and power surges. This type of breaker is capable of carrying up to 10A, and it has a reset time of 2 seconds.
