Circuit Breakers: 219-3-39673-7R5 application field and working principle

Circuit Breakers are a key component in the design of modern electrical systems, providing protection against electrical hazards and equipment damage. The 219-3-39673-7R5 is a thermal-magnetic type circuit breaker. It may be used in AC and DC applications ranging from 600VAC to 1500VAC, and up to 1500VDC.The 219-3-39673-7R5 is suitable for a variety of applications including industrial control panels, machine tool circuits, conveyor circuits, lighting circuits, power distribution panels, and electric vehicles. It can also be used in food processing and medical applications, as well as construction and agricultural equipment.The 219-3-39673-7R5 is a two-pole, three-phase circuit breaker, and it can be mounted in both horizontal and vertical orientations. It has a temperature rating of 65°C and can handle currents up to 73A. It has a compact design that fits easily into confined spaces.The 219-3-39673-7R5 is equipped with several features that enhance its performance and safety. It has an adjustable trip setting, which offers the ability to increase the tripping range in response to a fault current. This helps to reduce nuisance tripping when heavy inrush currents may be present. It also has trip free contacts, meaning that it will not reset once it has tripped, even if the fault current is removed. This ensures that the breaker stays in the off position until it is manually reset. It also has short circuit current rating (SCCR) protection, which helps to protect connected loads from overload and short circuit currents.The 219-3-39673-7R5 is designed with a thermal-magnetic trip unit, which is comprised of two subsystems. The thermal portion monitors continuous current and will trip the breaker if it exceeds the trip setting. The magnetic portion is an instantaneous trip element that reacts to extremely high currents and provides virtually instantaneous protection from short circuits.As with any circuit breaker, it is important to properly size it for the application. Generally, the size of a circuit breaker should be at least 125% of the full load current of the load that it is protecting. If the 219-3-39673-7R5 is going to be used in an NC contactor application, it should be sized to 6x the contactor full load current.The 219-3-39673-7R5 is designed to provide protection against overloads and short circuits, and is suitable for a wide variety of applications. It has several features that make it an effective choice for system protection, and its easy installation and compact design make it an ideal option for panel builders and electricians alike.
