描述 Description

The Thermally Protected High Energy, TPHE, Series is designed for safe disconnection of the Varistor from the circuit due to abnormal operating conditions. The TPHE Series is designed to withstand the rigors of UL1449 4th Edition Type 1 and Type 2 applications while still meeting the requirements of typical High Energy Varistor applications. The FSS design is for new and existing applications requiring high current surge capabilities, with integrated thermal protection accommodating form,and fit allowing for a drop in replacement for existing product offerings.
The FSD design is also for new and existing applications. It is packaged in a DIN-RAIL mounting configuration. The FSD design is available with 1, 2, 3, and 4 pole configurations for Delta and Wye connections.
The FSP design is similar to the FSS. It utilizes a smaller package to accommodate lower profile applications
