Circuit breakers form a crucial part of any electrical or electronic system. They are used to instantly switch off a circuit in case of an overload or short circuit. The 209–3–2988–919 circuit breaker is one of the most efficient circuit breakers available. This article will discuss its application field and working principle in detail.

Application field of 209-3-2988-919

The 209–3–2988–919 is a UL 489 listed circuit breaker primarily used in the commercial and industrial electrical applications. It is suitable for branch-circuit protection in various areas such as schools, hospitals, power panels, and other industrial settings. It is designed for use with 277/480-Volt AC, three-phase wye systems. It is available via a two-pole or three-pole assembly.

Working principle of 209-3-2988-919

The 209–3–2988–919 circuit breaker contains a set of thermal and magnetic trip mechanisms that protect the circuit from any overload or short circuit conditions. When the current passing through the circuit rises beyond a pre-defined safe level, the circuit breaker trips and interrupts the flow of electricity to the circuit. This ensures complete safety of the electrical equipment connected to the circuit. The circuit breaker has a built-in reset switch for manual resetting and a reset button with indicator lights for manual adjustments.

The 209–3–2988–919 circuit breaker also features an adjustable instantaneous trip setting that allows for the adjustment of the trip current level to the desired level. This feature is useful for protecting circuits from short-duration overloads. In addition, the circuit breaker has a long-life bimetallic trip element which offers enhanced performance and faster tripping times. The circuit breaker also has a safety interlock and an adjustable trip unit that helps to minimize nuisance trips and false alarms.

In conclusion, the 209–3–2988–919 circuit breaker is an efficient and reliable device designed for commercial and industrial applications. It offers advanced features such as adjustable current settings for overload protection, a long-life bimetallic trip element for faster tripping times, and a safety interlock for added protection. It is a UL 489 listed circuit breaker and is highly recommended for industrial use.
