Circuit breakers are devices that protect electrical systems from damage caused by sudden overcurrents or short circuits. The 4439.0005 model is designed for use in circuit breaker applications that require compact size, high amperage, and quick response. It is particularly suited for applications such as motor protection, safety shutoffs, and control of automatic power sources.

The 4439.0005 operates on a direct-activated thermal release principle. It is equipped with a electromechanical solenoid actuator that initiates the electrical contact when the set current is exceeded. When the set current limit is exceeded the solenoid helps to disengage the electrical contactor, breaking the circuit and protecting both the load and the switch mechanism. A built-in thermal release system adds a second level of protection, providing additional safety in the event of a persistent overload or short circuit.

The 4439.0005 circuit breaker has a maximum amperage rating of 4000 amps, making it suitable for use in a variety of industrial applications. The device is also UL listed and CSA certified, making it safe and reliable for professional applications. The breaker has a compact design and is rated for use in indoor or outdoor environments.

The main benefits of the 4439.0005 circuit breaker are its compact size, high amperage rating, and quick response time. The device is easy to install and has a low maintenance profile. The breaker is a cost-effective solution for a wide range of industrial applications, providing reliable protection and safety in high-amperage applications.

In summary, the 4439.0005 circuit breaker is a reliable, cost-effective solution for high-amperage applications. The device’s quick response, high amperage rating, and compact size make it an ideal choice for a variety of applications. The device is UL listed and CSA certified, providing peace of mind that your installation will be compliant with the safety standards.
