About 140UE-J4X3

The 140UE-J4X3 circuit breaker is a molded case circuit breaker by Allen-Bradley with the capability of providing reliable interrupting capacities that are designed for branch circuit protection and motor isolation protection. The Allen-Bradley 140UE-J4X3 molded case circuit breaker has an operating mechanism which includes an adjustable thermal function as well as a fixed magnetic function. One thing about this operating mechanism is that it boosts the performance of the 140UE-J4X3 circuit breaker since it uses 2 different fault-detection ways. These two ways normally detect various types of current, which improves the effectiveness of the circuit breaker. In addition to the branch circuit protection, the Allen-Bradley 140UE-J4X3 molded case circuit breaker also offers overload protection for motors. For additional protection, the breaker’s feeder circuit conductors must be connected to an upstream protective device, which eliminates the need for extra protection for the 140UE-J4X3 circuit breaker.



 



The 140UE-J4X3 molded case circuit breaker has an operating voltage range of 400 Volts to 525 Volts, with a rated operational current of 250 Amps. Its adjustable motor current range is 20 Amps to 250 Amps. There are several accessories that can be added to boost the overall performance of the 140UE-J4X3 molded case circuit breaker, and these accessories range from connecting modules to screw adapters, as well as metal housings. Other accessories like extension shafts, anti-tamper shields, and locking tags can also be used. Because of the use of the thermal mechanism, the 140UE-J4X3 circuit breaker must be installed in an environment with a stable temperature. If the 140UE-J4X3 circuit breaker is installed in an environment with very high temperatures, it can have an impact on the breaker’s trigger temperature, which can lead to malfunctioning and faults during its operations.
