Circuit breakers are electrical safety devices used to protect electrical power systems from being disturbed by overcurrent or short circuits. The 219-3-2R-2911-31 is a type of circuit breaker designed for medium voltage loadcenters in industrial and commercial applications. It is a three-pole, two-position, thermal/magnetic circuit breaker.

The 219-3-2R-2911-31 circuit breaker is designed to detect both thermal overload and short circuit conditions and react accordingly. Under normal conditions, the breaker operates in the closed position. When an overload or short circuit condition arises, an internal thermal-magnetic trip system releases a mechanism that opens the breaker, interrupting the circuit and protecting the equipment.

The device is based on an industrial-grade design featuring a double-break mechanism and highly reliable contacts. The current ratings range from 20 amps to 800 amps. It features adjustable short-time delay (before an overload trip) that can be set to 3-15 seconds. This adjustable delay is particularly useful in applications that may have high inrush currents.

The breaker is also tested and certified to UL489 and UL1077 standards, making it suitable for use in residential, commercial, and industrial applications. It is designed to provide maximum protection from overload, short circuits, and ground faults to both personnel and equipment.

Overall, the 219-3-2R-2911-31 circuit breaker is a reliable and efficient device designed for a wide range of applications and is suitable for use in residential, commercial, and industrial settings. The device is UL certified to ensure maximum safety, and its adjustable short-time delay offers greater flexibility for applications with high inrush currents.
