4404.0003 Circuit Breakers: Applications and Working Principle

Circuit breakers are devices designed to protect electrical systems from damage due to overload, short circuits or other overload conditions. The 4404.0003 is a robust and reliable type of circuit breaker typically used in industrial, commercial, and utility applications. In this article, we will take a closer look at the applications of the 4404.0003 circuit breaker and its working principle.

Applications

The 4404.0003 is a three-pole, molded-case type of circuit breaker. It is used in many different applications, including residential, commercial, industrial and utility installations. It is often found in main power panel systems and secondary service panel systems. It is also used in motor control systems, panelboards, switchboards and other spaces in which it is necessary to have protection from electrical overloads.

Working Principle

The 4404.0003 is designed to prevent electrical systems from damage due to overloads, short circuits or other overload conditions. The device works by using a switch or the magnetic force of an electromagnet to trip the breaker when the current or voltage reaches a certain level. This helps to limit the amount of energy released during an incident.

The 4404.0003 uses a thermal-magnetic operation system. When a circuit is subjected to a current or voltage level higher than the one it’s rated for, internal components heat up. The temperature rises, acting on the circuit breaker’s heat element. This causes the switch to trip, and the breaker will immediately disconnect the electricity supply.

In addition, the 4404.0003 is equipped with a magnetic field sensor which is able to detect faults which may be the result of a short circuit in the system. This helps to ensure that the breaker is able to detect any faults and trip before they cause any damage.

Conclusion

The 4404.0003 is a three-pole, molded-case type of circuit breaker designed for use in many different applications including residential, commercial, industrial and utility installations. It is designed to protect against electrical overloads and short circuits by using a thermal-magnetic operation system. The 4404.0003 is a reliable and robust circuit breaker, with a magnetic field sensor which helps to ensure that the breaker is able to detect any faults and trip before they cause any damage.
