140G-J6F3-D15

The 140G-J6F3-D15 circuit breaker is a magnetic and thermal circuit breaker that has the ability to interrupt a current and at the same time to protect the system from short circuits and abnormal currents. This circuit breaker has been manufactured by Allen-Bradley and it is part of the 140 series. It has been proven that the use of circuit breakers in a closed-loop system can provide efficient protection against these common kinds of abnormal conditions in industrial mechanical systems. The Allen-Bradley 140G-J6F3-D15 magnetic and thermal circuit breaker belongs to the J frame subset of the 140 series. This frame provides a current rating of 250 Amps and an interrupting capacity of 65 kiloamps. This circuit breaker is an adjustable thermal and magnetic circuit breaker. It comes with adjustable features that can be measured and programmed according to the needs of the application or the protection level that is required.

The Allen-Bradley 140G-J6F3-D15 magnetic and thermal circuit breaker works with 3 poles in conjunction. These poles come with a mechanism that enables them to be connected to each other, meaning that once a pole has detected a condition that requires immediate interrupting, this condition is communicated to the other 2 poles and the 3 of them all proceed to perform the interrupting action at the same time. The Allen-Bradley 140G-J6F3-D15 magnetic and thermal circuit breaker is affected by extremely high temperatures. It can withstand an operating temperature range of 0 to 40 degrees Celsius and when it is used in temperatures below 0 degrees Celsius, it may experience a slow-down in the velocity of its detection process due to possible ice formations around the enclosure of the breaker.
