Circuit Breakers

Circuit breakers are an essential component in any electrical power system. They are used in residential application, commercial and industrial applications, as well as in power transmission and distribution systems. The use of circuit breakers to protect these circuits from damages caused by excessive current in the circuit has become standard practice.

4400.0019 Application Field and Working Principle

The 4400.0019 circuit breaker is a trip-free mechanism and is used in residential and light commercial applications. This circuit breaker is designed to protect circuits used in lighting, heating and ventilation, heating and air conditioning, motor controllers and heating and cooling equipment. This breaker is rated for use in branch and feeder circuits as well as panelboards and switchboards.

The 4400.0019 circuit breaker has a simple working principle. It contains a thermal-magnetic trip element that is essential in the functioning of the breaker. The thermal-magnetic trip element is responsible for protecting the circuit from short circuit faults and over currents. This element detects excessive current in the circuit and trips the breaker, which then isolates the circuit and prevents any further damage to the circuit. In other words, the breaker acts as a safeguard against excessive current in the circuit.

The 4400.0019 Circuit Breaker also has a manual reset button on the front of the breaker. This button is used to reset the breaker after it has been tripped. The breaker can be reset either manually or automatically. To reset the breaker manually, the reset button must be pushed to initiate the resetting process. The breaker can also be reset automatically by a reset solenoid.

In addition to its trip-free design, the 4400.0019 Circuit Breaker has a built-in over current protective device. This device helps to protect against short circuit faults and is essential for providing the necessary protection for circuit breakers in electrical power systems. It is rated for use in branch, feeder and switchboard circuits.

The 4400.0019 Circuit Breaker has a quick make and break cycle. This means that it can be quickly energised and de-energised, making it suitable for applications that require very fast on/off cycles such as motor control applications.

The 4400.0019 circuit breaker is designed to be used in residential and light commercial applications. It is a cost-effective and reliable option that provides the necessary protection against short circuits and over current. The built-in over current protective device, quick make and break cycle, and manual reset button make this circuit breaker an excellent choice for applications that require reliable circuit protection.
