The Allen-Bradley 140G-G3C3-C90 is a sophisticated molded case circuit breaker engineered to safeguard electrical systems by promptly interrupting excessive or irregular currents, ensuring superior reliability compared to traditional fuses. This breaker employs both thermal and magnetic detection mechanisms across three poles, enabling it to quickly respond and reset after fault conditions, which underscores its suitability for modern applications where frequent circuit interruptions may be necessary. With an interrupting capacity of 65 Amps and a current rating of 90 Amps, the 140G-G3C3-C90 is ideal for use in conduit protection or as a control panel switch, functioning optimally within a temperature range of 0 to 40 degrees Celsius.
