4420.0484 Circuit Protection

Circuit Breakers are a widely used safety technology designed to protect electrical circuits from short circuits and other potentially damaging conditions.

The number 4420.0484 is a classification number for a specific type of circuit breaker. It is a double-break design manufactured by Connecticut Electric, Inc. and is designed for indoor and outdoor applications within the voltage range 480 to 600 volts AC. It features a totally enclosed, non-ventilated design for superior protection in both indoor and outdoor applications. It is designed to provide protection against overcurrent and short circuits in circuits supplying power to industrial equipment.

This particular model of circuit breaker is known as an "application specific" design, meaning that it is designed to be used in very specific applications and to meet specific needs. It has been designed and tested to meet NEC and UL standards, making it safe and reliable for operation. It also features a thermal-magnetic trip mechanism, which allows it to be adjusted to different load requirements without the need for manual intervention.

The working principle of this circuit breaker is quite simple. Essentially, it protects the circuit by opening the connection when the current exceeds the specified limit. The breaker also monitors the rate of rise of the current, and if it detect a surge in the rate of current rise, it trips and opens the circuit.

The 4420.0484 is a reliable and safe circuit breaker that is suitable for a wide variety of applications. It is used in residential and commercial buildings, in electric power substations, and in factories and large industrial plants. Its application specific design makes it ideal for particular applications, such as providing protection for motor control circuits. Its protection is also essential for the safety of personnel working in industrial or hazardous areas.

In conclusion, circuit breakers are a vital component of any electrical system. The 4420.0484 is a well-designed and highly reliable circuit breaker that is suitable for a variety of applications. It provides superior protection against overcurrents and short circuits, and its thermal-magnetic trip mechanism allows for easy adjustment to different load requirements. It is a reliable and safe choice for residential and commercial applications, as well as for industrial power substations.
