Circuit Breakers

A circuit breaker is a device that selectively interrupts a circuit in case of overload or short-circuit condition. The 4430.1328 is a compact, reliable and economical circuit breaker designed for use in a variety of applications. It is designed to provide overcurrent protection for electrical systems.

4430.1328 Application Field

The 4430.1328 circuit breaker offers advanced protection capabilities in a broad range of applications, such as residential and commercial buildings, industrial machines, power systems, data processing centers, and renewable energy systems. It is suitable for protection of distribution systems, office buildings, hotels, shopping centers, projects, factories, and other high-risk environments where the stability of the system is paramount.

The 4430.1328 is certified for use in hazardous locations, providing a higher level of safety compared to other types of circuit breakers. It is designed to operate safely even in harsh environmental conditions, including temperature ranges from 0°C up to 65°C, with up to 95% relative humidity. It is suitable for installation in areas exposed to dust, moisture, and vibration, ensuring that it will provide reliable protection for any application.

The 4430.1328 is available in a variety of configurations, including single and three-phase, and accommodates 2–6 circuits in one housing. This allows the circuit breaker to be used in applications requiring several overloads.

4430.1328 Working Principle

The 4430.1328 is a thermal-magnetic circuit breaker that uses both thermal and magnetic forces to provide protection. The thermal protection function is achieved by a special bimetallic element, while the magnetic protection is provided by a magnetically actuated switch. When an overcurrent passes through the circuit breaker, the thermal element will heat up, actuating the switch to open the circuit and disconnect the load from the power source. The magnetically actuated switch then acts as a backup protection to prevent further disturbances in the event of an overload, short circuit, or other fault.

The 4430.1328 circuit breaker uses an electronic current sensing device to protect against overcurrents. The sensing device monitors the current passing through the breaker and when it detects that a specified overcurrent is present, it triggers the circuit breaker to automatically open. This allows the user to quickly identify the cause of an overcurrent and shut down the system to prevent further damage.

The circuit breaker is also designed to provide protection against reverse polarity, which is a common problem in some systems. If reverse polarity is detected, the breaker will open, isolating the load from the power source. This ensures that no damage can occur and prevents the problem from reoccurring.

Conclusion

The 4430.1328 is a reliable and economical circuit breaker designed for a wide range of applications. It offers advanced protection capabilities and is suitable for use in hazardous locations. It is designed to operate safely even in extreme environments and is equipped with features to protect against overcurrents, reverse polarity, and other faults. For these reasons, the 4430.1328 is a great choice for any system that requires reliable and comprehensive protection.
