T 3575 PHASE SWITCH – Class B 130°C – Class F 155°C

VOLTAFASE T 3575 flexible insulating composites are made by combining a polyester film interleaved with two layers of polyester non-woven fabric. The polyester non-woven layer increases the polyester's resistance to thermal aging.

Its highly absorbent nature facilitates impregnation with paints or insulating resins, furthermore its "roughness" makes it less slippery, therefore ideal for use as a separator or bezel.

Maximum Operating Temperature: Class B/F – 130/155°C (IEC 60626)
Class F – 155°C (UL 1446)
Minimum Operating Temperature: Resin -60°C / Polyester -60°C
