Allen Bradley 1492 Trip Curve and AMP Rating
Need help determining the trip curve, AMP range and number of poles for a Allen Bradley 1492-SP miniature circuit breaker? Simply find the sequence of letters and numbers just below the 1492-SP part number and the letter (B,C, or D) is the trip curve and the number (0.5 through 63) would be the AMP range. To determine the number of poles, just count how many attached pieces there are that look just like the image above. For example, if you have a 1492-SP circuit breaker with a letter C and number 16 and it has two attached pieces that look like above, then you would have a C10 2 pole breaker. Furthermore you can also find the complete product part number on the side of the breaker, and should resemble something similar to 1492-SP1C100.
