140U-J2L3-D16

The 140U-J2L3-D16 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 circuit breaker is 400 to 480 Volts AC and the current rating is 160 Amps. The 140U-J2L3-D16 Molded Case Circuit Breaker comes with 25 Kiloamps of interrupting rating and 11.4 pounds of shipping weight. The protection type of the breaker is the electronic protection type (LS, long and short time). The electronic trip unit of the circuit breaker has the ability to tailor the tripping characteristics for the application at hand. It electronically replicates the functions of the mechanical overcurrent device.

The 140U-J2L3-D16 Molded Case Circuit Breaker provides enhanced operator safety and facilities to reset it after a fault while fuses can only be used once. This MCCB provides thermal protection for branch circuits and control panels. Thermal protection can be provided through the use of electronics that can provide adjustable overcurrent protection for the application at hand. The electronic trip circuit breaker may have a wider temperature range than other breakers and it is rarely affected by ambient temperature fluctuations. Its high current ratings allow operators to use the 140U-J2L3-D16 circuit breaker in heavy-duty applications. It can be used with applications that require a high current rating, adjustable strip settings, or combinations of both factors. The electronic trip unit provides advanced protection with additional trip functionalities and it has the flexibility to customize the thermal protection with multiple trip settings such as the instantaneous trip and the ground fault. This molded case circuit breaker is UL listed, CSA listed, and KEM certified to meet various industrial standards.
