Circuit breakers are electrical switching devices that control the flow of current to specific areas in a circuit. Circuit breakers can be used to provide circuit protection and isolation, among other critical applications. The 4419.9004 circuit breaker is intended to protect electrical circuits from overvoltage, short circuits, and overcurrent conditions. It is designed to automatically interrupt the current in the case of an overcurrent or short circuit event.

The 4419.9004 is a heavy duty three pole circuit breaker with wye-delta connections and adjustable trip settings. It is rated for 440A at 600VAC and is UL 489 listed for general duty applications. The circuit breaker also has provisions for a shunt trip and auxiliary contacts for remote operation and control. It is typically used in applications that require overload and short-circuit protection as well as phase-balancing and under-voltage protection.

The 4419.9004 has three adjustable trip settings: current, voltage, and ground fault. The adjustable trip settings can be used to tailor the circuit breaker’s protective action to fit a particular application. The trip settings are adjusted using a selector switch located on the circuit breaker’s front plate.

The 4419.9004 also has a thermal-magnetic trip unit which combines both a thermal element and a magnetic element. The thermal element is responsible for detecting temperatures that are higher than normal and prevents the circuit breaker from overheating, while the magnetic element senses current levels and detects the presence of a short circuit. When either the thermal or magnetic elements are tripped, the circuit breaker will automatically disconnect the power supply and prevent further damage to the circuit.

The 4419.9004 has two operating mechanisms, a manual reset and an automatic reset. In a manual reset, the breaker must be manually reset after the power has been disconnected. An automatic reset is initiated when the overcurrent or short circuit event has ceased and the breaker automatically resets itself. The 4419.9004 is also equipped with test buttons to check the proper operation of the circuit breaker before and after power is applied.

The 4419.9004 is a versatile circuit breaker that is suitable for a wide range of applications, including electrical panels, motor control centers, and other industrial equipment. It is designed to provide reliable protection against overcurrents, short circuits, and other hazardous conditions. With its adjustable trip settings, it can be tailored to fit the needs of any given application, and its test buttons offer added protection before putting the circuit into operation.
