The Allen-Bradley 140G-H2C3-C15-KA Molded Case Circuit Breaker is an H-Frame fixed thermal and fixed magnetic protection device that is designed and built in order to provide overcurrent and overload tripping capabilities for automatically disconnecting downstream circuits. Its current rating is 15 Amps, with a thermal trip of 15 Amps and a magnetic trip of 400 Amps. It also has an interrupting rating or breaking capacity of 25 kA. The Allen-Bradley 140G-H2C3-C15-KA Molded Case Circuit Breaker is equipped with 3 poles, but there is also a 4-pole version available. Another useful feature of this molded case circuit breaker is an additional, factory-installed, 250 Volts rated auxiliary contact that can be used in any application where the ON/OFF status of the molded case circuit breaker needs to be monitored or where the users need to control an external process according to a specific configuration.

Molded case circuit breakers like the Allen-Bradley 140G-H2C3-C15-KA Molded Case Circuit Breaker are employed in different applications in order to provide overcurrent protection for industrial machinery, application processes, and their wiring by opening automatically before the current reaches dangerous values for a too long a period of time. These excessive current conditions, if left unmonitored, can produce high-temperature rises in conductors and their isolation devices, and this can cause fires and explosions with serious consequences in terms of both material damage and personal injuries or even death. Another key feature of the Allen-Bradley 140G-H2C3-C15-KA Molded Case Circuit Breaker is that it is suitable for manual operation, providing a means for connecting or disconnecting a control panel. This circuit breaker's parameters for thermal and magnetic tripping are not user-configurable. Instead, they are pre-set by the factory.
