About 140U-J2X3
The 140U-J2X3 Molded Case Circuit Breaker (MCCB) is a high-performance compact breaker from Allen-Bradley/Rockwell Automation. It has a size J frame, 3 poles, and 250 Amps of frame current. The rated operational voltage of the breaker is 400 or 480 Volts AC and the current rating is 250 Amps. It comes with 25 Kiloamps of interrupting rating and it has 11.4 pounds of shipping weight. The 140U-J2X3 Molded Case Circuit Breaker provides thermal overcurrent protection and short circuit protection for industrial panel control applications. It can be used as a current limiting circuit breaker that operates faster than traditional UL 489 circuit breakers. The MCCB consists of a magnetic trip unit that can provide short circuit protection. As the short circuit current increases, it provides a faster interruption time.
This CSA listed 140U-J2X3 Molded Case Circuit Breaker features common accessories that allow for maximum flexibility. It has an arc chamber that performs several important functions to provide short circuit protection. The chamber surrounds the switching contacts to open it during a short circuit. During installation, make sure to avoid atmospheres with moisture or corrosive elements. This electromagnetic device provides the facilities to open a circuit manually and automatically under short circuit or overload conditions. It can be used as a branch short circuit device or branch protective device for a motor load. This 140U-J2X3 Circuit Breaker is suitable for energy-intensive systems such as commercial and industrial high power applications. It can be used in motor control applications to provide overload protection without being tripped during the inrush current. This molded case circuit breaker is suitable to use in electrical feeder circuits that provide power to large distribution boards.
