The 140G-J6F3-D25 circuit breaker is an adjustable magnetic and adjustable thermal circuit breaker manufactured by Allen-Bradley. Circuit breakers like this one are used as protective units in any machine system or as a way to stop the operation of specific equipment. It can also be attached to and operate as the disconnect device of any control panel. These circuit breakers are usually included in closed-loop systems where the current tends to vary. The installation place of the Allen-Bradley 140G-J6F3-D25 adjustable magnetic and adjustable thermal circuit breaker must be a clean location with the right amount of ventilation, and without high amounts of dust and dirt. If it is used in a place with an altitude higher than 1000 meters above sea level, the 140G-J6F3-D25 circuit breaker will not operate at its maximum efficiency rating. The breaker will need to be derated for every 1000 meters of additional elevation. The temperature should not exceed 40 degrees Celsius.
The Allen-Bradley 140G-J6F3-D25 adjustable magnetic and adjustable thermal circuit breaker has a quick recovery process, meaning that after an interrupting mechanism has been activated, it can be put back into operation immediately, although it is recommended to perform periodic inspections to determine whether the breaker is in good enough condition to keep operating or if it needs to be replaced. The Allen-Bradley 140G-J6F3-D25 adjustable magnetic and adjustable thermal circuit breaker employs mechanical elements that get heated up by the current and thus perform a movement. The magnets are specially used to detect short circuit currents. The poles present in the circuit breaker are in charge of performing the interrupting action when necessary.
