The Allen-Bradley 140G-J6F3-D20-KJ Circuit Breaker is a 3-pole, 200 Amps, J-Frame molded case circuit breaker with an interrupting rating or breaking capacity of 65 kA, adjustable thermal and magnetic tripping points, a 160 Amps current rating, and a built-in 24 Volts DC auxiliary contact. The thermal tripping point is user-adjustable through screw-type setting wheels in a current range from 140 to 200 Amps, and the magnetic tripping point can also be adjusted between 1k and 2k Amps. The main application for the Allen-Bradley 140G-J6F3-D20-KJ Molded Case Circuit Breaker is the protection of downstream-connected loads by providing manual disconnection and automatic disconnection functions from the main electrical AC utility line when the current of the circuit dangerously increases in magnitude during a prolonged period.
The Allen-Bradley 140G-J6F3-D20-KJ Molded Case Circuit Breaker comes in a sturdy casing so that it can resist the tough environments normally found in most industrial work sites. Nevertheless, it is recommended for the users is to install it inside an appropriately designed enclosure, so that the lifespan of the circuit breaker can be extended by avoiding its direct contact with humid air and dust. The embedded 24 Volts DC auxiliary contact enables the possibility of external monitoring of the Alle- Bradley 140G-J6F3-D20-KJ Molded Case Circuit Breaker so that the users can initiate different procedures or signal events according to with their control algorithms and application needs. Other accessories are also available for installation in this circuit breaker such as additional auxiliary contacts, under-voltage trip, trip contact blocks, and the shunt trip.
