4420.099

Circuit breakers are electrical devices that automatically disconnect a circuit when the current becomes too high for safety. The 4420.099 circuit breaker offers extra protection against intermittent and extreme high-current surges. It is designed to quickly detect and open the circuit in order to minimize damage from electrical overcurrents.

Application field

The 4420.099 circuit breaker is a valuable device for electrical systems that require high-level short-circuit protection. They are usually found in industrial, residential, commercial and military applications. Some common applications include motor control, data centers, welding machines, solar-battery storage systems, emergency lighting, emergency standby generators, and HVAC systems. Not only is it capable of providing reliable protection, the breaker can monitor and detect overloads and provide emergency shut-off capabilities when needed.

Working Principle

The 4420.099 circuit breaker operates by sensing abnormal current levels and quickly cutting off the electrical power to the circuit. It functions by detecting an overvoltage or an undershoot condition of an existing circuit. In normal operation, the circuit breaker will measure the current flow in the protected circuit while it is on. When the amount of current reaches a predetermined level, the breaker will trip and quickly shut down the circuit. It is designed to prevent serious damage from excessive current levels.

The 4420.099 circuit breaker is designed to open when the current reaches a specific level and will remain open until the current drops back to a normal level. Once the current returns to a normal level, the breaker can be reset manually or automatically. This type of breaker is designed to protect a circuit from short circuits and low-level over-voltages, which could potentially cause a fire or equipment damage.

The 4420.099 circuit breaker is a reliable device that offers superior protection against current surges and shorts. It is designed to provide quick and efficient protection against costly and dangerous overvoltages or undershoots. With its reliable and robust design, the breaker ensures that current levels remain stable and within acceptable limits, preventing serious damage to the protected circuit.
