What 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.
