Circuit Breakers play an essential role in protecting both personnel and electrical equipment from harm due to overcurrents, short circuits, or other dangerous electrical conditions. The 203-2-4014-1 is a circuit breaker designed to protect electrical systems as required by UL 489, UL 1077, CSA C22.2 and more. It is a quick action, three-pole, general duty circuit breaker featuring standard 40A and 65A frame sizes and is UL-rated up to 1,600 amps.

The 203-2-4014-1 features therm-magnetic trip action, with an adjustable trip setting of 18-21 amps. It offers protection against short circuits, overloads, overcurrents, and other common electrical hazards. This type of circuit breaker is designed to meet the requirements of UL 1083: Special Purpose Systems and Devices Requiring Supplementary Overload Protection. It is also listed under UL 489, as well as CSA C22.2 No. 62.

The 203-2-4014-1 has a wide range of applications in the industrial, utility, residential, and commercial sectors. In particular, it is ideal for use in power systems, control systems, branch circuits, panel boards, and transfer switches. It is also suitable for replacing existing circuit breakers in older commercial and industrial buildings. The 203-2-4014-1 is especially useful in situations where a wide variety of current draw is expected, as it can handle up to 500 volts of current without tripping.

The 203-2-4014-1 features a wide range of working principles. It has an adjustable set point and features a one-pass thermal trip. The adjustable trip setting allows for easy calibration of the breaker, ensuring that it will respond exactly as expected. Additionally, it includes an adjustable current rating, allowing you to select the required current level for the application. The adjustable trip setting also allows you to select the maximum current the breaker should allow before tripping.

The 203-2-4014-1 also features an instantaneous trip mechanism. This ensures that when a short circuit occurs, the breaker will trip off very quickly, minimizing damage from overcurrents and arc flashes. In addition to this, it also features a holding current setting. This setting allows you to select the current the breaker should hold after tripping. This helps to ensure that the breaker will remain tripped off until manually reset.

The 203-2-4014-1 is a versatile, safe, and reliable circuit breaker. It is easy to install and use, and its adjustable trip setting and built-in diagnostics make it suitable for a wide variety of applications. Its one-pass thermal action and adjustable current rating make it perfect for high-current environments, such as industrial plants and utility substations. Additionally, its holding current setting and instantaneous trip mechanism make it an ideal choice for safety-critical applications.
