Circuit Breakers

Circuit breakers are electrical components designed to interrupt the flow of current in an electrical circuit in case of a potentially dangerous overload or short circuit. This is a crucial safety feature in any wiring system – as it prevents accidental fires caused by faulty electrical wiring, overheating, and other problems.

The 4420.0199 circuit breaker is a product of the SIEMENS Corporation. This particular model is designed for applications up to 440V AC and 3000A, and is UL 1077 listed for safety. It is built for residential, commercial, and industrial applications and is reliable and easy to install.

Application Field

The main application field for the 4420.0199 circuit breaker is as an overload thermal protector in residential, commercial, and industrial wiring systems. This model is primarily used in installations which require a high degree of safety, such as hospitals, shopping malls, industrial buildings, airports, and factories. It is also suitable for use in high temperature and vibration environments, such as machine rooms and power plants.

This circuit breaker is also used to protect against potentially dangerous electrical surges. It monitors the incoming power supply and trips when it detects a potentially damaging surge, helping to protect sensitive electrical equipment from damaging power surges.

Working Principle

The 4420.0199 circuit breaker operates on an electrical overload/short circuit detection principle. The device monitors the AMP draw of the circuit and trips when it detects an overload or short circuit. It provides both overload protection and short circuit protection.

The device also features adjustable thermal protection, which protects against excess temperature. This is done via a bimetallic strip located in the body of the device. When the temperature in the circuit exceeds the set limit, the bimetallic strip bends and trips the breaker. This helps to prevent electrical fires by quickly cutting off the power supply in the event of an excess temperature.

The 4420.0199 circuit breaker is designed to be reliable and easy to install. It features a self-locking mechanism which helps to ensure that the breaker is securely installed, while an easily accessible shutter allows for quick inspection and testing. It is also equipped with a manual reset button, which allows it to be manually switched off and on without the need for an external power source.

Finally, the 4420.0199 circuit breaker is UL 1077 listed for safety, meaning that it has gone through rigorous testing by the Underwriters Laboratories to ensure it meets strict safety standards. This helps to ensure that the device is durable and reliable, and that it won’t cause any electrical fires or other risks.

The 4420.0199 circuit breaker is an excellent choice for any wiring system that requires overload and short circuit protection, as well as thermal protection. It is easy to install, reliable, and UL 1077 listed for safety, making it a great choice for any home, commercial, or industrial wiring system.
