June 26, 2014 - Mersen extends range of STP6903 DIN-rail surge protective devices to include UL 1449 3rd Edition Recognized ratings up to 690VAC for 3-Phase WYE configurations. The STP 690VAC offerings are intended for applications such as Oil & Gas and Wind Power where 690VAC voltage configurations are commonly used. Mersen’s STP series is both UL and IEC certified to the latest industry standards and feature Mersen’s TPMOV Technology inside.
