4400.003

Circuit Breakers

Circuit breakers are a type of device that is used to protect the electrical circuit from overload currents. These devices detect excessive current levels and trip the switch, cutting off the circuit current in order to protect the circuit from damage.

The 4400.003 is a type of circuit breaker that is specially designed for high-voltage applications. It is made of high-quality materials and components that allow it to withstand high voltage levels. This type of breaker is also known as a shunt trip circuit breaker. It is equipped with a built-in trip mechanism that can be activated by an external source such as a relay, switch, or sensor. When tripped, the mechanism will open the contacts, cutting off power to the circuit.

Application Field and Working Principle

The 4400.003 circuit breaker is used in high voltage applications such as in substations, power plants, mining operations, and industrial plants. It is typically used in applications where the voltage is usually over 600 volts. The 4400.003 can be used in three-pole or four-pole configurations. It is also designed to handle large current levels as well as a wide range of ambient temperatures ranging from -40°C to +60°C.

The working principle of a 4400.003 circuit breaker involves the use of a trip coil, armature, and contacts. The trip coil is an electromagnet that is used to open the breaker contacts when an overcurrent occurs. The coil is actuated by a current transformers. When an overcurrent is detected, the current transformers send a signal to the trip coil, which then trips the armature which opens the breaker contacts. This causes the electrical circuit to be disconnected, thus protecting the circuit and equipment.

The 4400.003 also has a number of safety features that are designed to prevent unwanted trips and false trips. The trip coil is designed to be temperature compensated. This means that it will respond to a set amount of temperature, preventing the breaker from engaging mistakenly during a temperature change. There is also a reset lockout feature that will, when activated by an external source, prevent the breaker from tripping in the event of a fault.

Advantages of 4400.003 Circuit Breakers

The 4400.003 is a high-voltage breaker that is designed to be both safe and reliable. Some of the advantages of having a 4400.003 circuit breaker include:

• Able to handle large currents.
• Able to withstand extreme temperatures ranging from -40°C to +60°C.
• Equipped with temperature compensation for improved protection.
• Trips fast in the event of a fault.
• Resistant to electromagnetic and radiofrequency interference.
• Designed to be resistant to wear and tear.

Conclusion

The 4400.003 is a type of circuit breaker that is designed for high voltage applications. It is made of high-quality components and materials that allow it to withstand high voltage levels. It is equipped with a built-in trip mechanism that activates when an overcurrent is detected. This breaker also has a number of safety features that are designed to prevent unwanted trips and false trips. The 4400.003 is a reliable and safe breaker that offers a number of advantages over other types of circuit breakers.
