03/28/2011What does the 130B Suffix on PL Series Power Transformers mean
In approx. 1998, Tamura Corporation began marking our PLxx Series International Power Transformer Products with a –"130B” mark. This indicates that the Product is approved to a UL Class B 130 Deg. C Insulation System. Tamura UL File # E92957. The product maintained the same Construction materials and process, as before. The new recognition simply certifies the higher temp rating, as designated in Tamura’s Insulation System.This applies to the PL2.5-xx, PL5.0-xx, PL10-xx, PL20-xx, PL30-xx, PL56-xx, PLT20-xx, PLT30-xx and PLT56-xx series Catalog Products from Tamura Corporation.
