140G-G6C3-C20

The Allen-Bradley 140G-G6C3-C20 thermal and magnetic circuit breaker comes embedded in a protective case to provide protection against contact with different kinds of particles. It has been designed and distributed by Allen-Bradley /Rockwell Automation to protect electric circuits and conduits. This breaker belongs to the Allen-Bradley 140G series. The Allen-Bradley/Rockwell Automation 140G-G6C3-C20 thermal and magnetic circuit breaker is mainly used to interrupt the power to different wirings when the current flow exceeds safe levels or when it becomes a dangerous current for the conduit or the equipment attached. Short-circuit currents can cause permanent damage to equipment, panels, and conduits, and it can even cause a fire or create a dangerous condition for the users around it.

The Allen-Bradley/Rockwell Automation 140G-G6C3-C20 thermal and magnetic circuit breaker has a small size that helps to save space and it has a long lifespan that avoids high replacement costs. The thermal detection mechanism consists of metal bars that get heated up by the same current that flows into the conduits and the magnetic mechanism employs a magnet that detects short-circuit currents. These 2 mechanisms are combined with 3 poles that perform the opening/closing actions. The Allen-Bradley/Rockwell Automation 140G-G6C3-C20 thermal and magnetic circuit breaker has a current range of 20 Amps and an interrupting capacity of 65 kA. The breaker can operate at 80% of its current range when it is installed properly. There are no big requirements for the installation of the circuit breaker, it can be mounted in any position and the cables used are those that are rated for operations at 75 degrees Celsius. Before installing the breaker, its specifications need to be compatible with the current rating of the application.
