Circuit breakers exist to protect equipment from overloads and short-circuits, by providing a means for automatically interrupting the electric current. The IEGBX66-1REC5-36995-1-V circuit breaker is one such device and is used primarily in medium-voltage applications.

The IEGBX66-1REC5-36995-1-V circuit breaker is a type of electrical switch, which is used to control both electrical power and isolation such as controlling ignition systems. It is a two-pole switch, with each pole rated for up to 4,300 amps. It is both current and temperature limited, with an adjustable trip setting. When the voltage or current in the circuit reaches a dangerous level, the breaker world trip and begin the motorized reset procedure.

The IEGBX66-1REC5-36995-1-V circuit breaker is designed to work in three-phase power distribution systems. It is primarily used for medium-voltage applications such as commercial, industrial and utility operations. These circuit breakers can be used to protect motors, generators, transformers, and other equipment from damage caused by overcurrent and short-circuiting.

The working principle of the IEGBX66-1REC5-36995-1-V circuit breaker is based on the thermal-magnetic principle. The thermal-magnetic principle states that the time-current characteristic of the breaker is composed of two functions: an instantaneous current breaking function and a delay current breaking function. It also states that the values of these two functions depend on several factors, including the electrical characteristics of the device and the ambient temperature.

The instantaneous current breaking function is activated when the current in the breaker rises suddenly to an overcurrent level. When the overcurrent level is reached, a current-sensing device causes the breaker to trip. This current-sensing device uses a combination of a thermal element, a bimetallic strip, and a magneto-thermal element to detect the current in the breaker.

The delay current breaking function is activated when the electric current in the circuit reaches the trip setting value. This value is predetermined by adjusting the trip settings. If the current does not decrease to below the trip setting value within the predetermined time, the breaker will trip. The time-current characteristic of the breaker is strictly governed by the calibration of the trip setting value by the user.

The IEGBX66-1REC5-36995-1-V circuit breaker applies the thermal-magnetic principle to offer the user optimal protection in medium-voltage applications. Its adjustable trip-setting capability allows the user to tailor the breaker’s performance to the specific needs of the application. The breaker also features a motorized reset that allows for easy resetting of the breaker after it has tripped.
