The Allen-Bradley 140G-J6F3-D15 is a robust magnetic and thermal circuit breaker renowned for safeguarding industrial systems against short circuits and abnormal currents. As a part of the J frame subset in the 140 series, this circuit breaker features adjustable thermal and magnetic settings, ensuring tailored protection with a current rating of 250 Amps and an interrupting capacity of 65 kiloamps. Designed for efficiency, it employs a synchronized three-pole mechanism that promptly interrupts upon fault detection, while operating reliably within a temperature range of 0 to 40 degrees Celsius, albeit with potential performance reduction in sub-zero conditions.
