219-3-3438-1 Application Field and Working Principle

Circuit breakers are devices specifically designed to disconnect circuits and control the flow of electricity. 219-3-3438-1 circuit breakers, specifically, are most commonly found in residential homes and commercial areas, providing protection for a wide range of circuits and power systems. Considered a must-have in every home, circuit breakers serve to protect from dangerous levels of electricity that may cause injury or death and saves appliances from electrical overload and short-circuiting.

Circuit breakers, like 219-3-3438-1, are available in an ample variety of devices from miniature device-and-sea breaker combinations to sealed types that compactly fit automobile electrical systems. Furthermore, these devices are often categorized according to their operation and rated values in breaking capacities. While this particular device is mainly acclaimed for its usefulness in residential settings, due to the adjustments made to the “trip-free” feature, 219-3-3438-1 can also be used in alternative devices as well.

The 219-3-3438-1 circuit breaker is built with an adjustable overload trip setting, allowing for it to be used to control circuits which are subjected to frequent small overloads. It also includes terminals that make it easy to connect wiring to the device. When voltage or current through the 219-3-3438-1 reaches a dangerous level, due to overload or a short circuit, its integrated thermal-magnetic trip unit breaks the connected circuit within a few seconds. Its terminal points are shrouded and require tools to open it, safeguarding users from accidentally receiving a shock.

Included is also a manually reset handle that allows users to reset or ‘trip’ the breaker. This feature comes especially handy in a situation where breakers are frequently switched on and off to avoid high-current overloads. The reset also serves to break off an existing short circuit as well. The specification of the device also complies with both CUL and UL standards of safety to reassure the consumers of its durability and reliability.

The 219-3-3438-1 circuit breaker is not only made to assure the safety of users, but also the convenience and reliability of an appliance, high-powered system, or devices. Its manual reset (which also can be easily automated) allows for steady protection on costly appliances or systems and its portability and widely accepted rating makes it a must-have in the realm of circuit breakers.
