Specifications and availability subject to change. To use this chart: Read up from the ambient temperature to the curve, and across to find a correction factor. Multiply the breaker rating by the correction factor to determine the compensated rating. Calculate the overloads in terms of the compensated rating to use the published trip curve. www.tycoelectronics.com Technical support: Refer to inside back cover.
