Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.
Effective September 15, 2009 onward, all 2920L PTC products will be manufactured Halogen Free (HF). Existing Non-Halogen Free 2920L PTC products will continue to be sold until
supplies are depleted. Effective January 1, 2010, all 2920L PTC product will be manufactured and sold as Halogen Free by default, and the “HF” part number suffix code will be discontinued
