Emerson PowerSure™ TCS-HW Series (with NTI Technology)

The PowerSure TCS-HW Series TVSS features a two-stage design that provides superior protection for sensitive equipment and for ANSI/IEE c62.41 Location Category A applications. Utilizing bipolar Silicon Avalanche Diode (SAD) technology, the PowerSure TCS-HW Series can be incorporated into larger power protection or used as point-of-application protection. Hardwired into a single 15- or 20-amp AC circuit, the PowerSure TCS-HW Series places protection at, or near, the critical load. The field-tested design ensures continuous  protection in the most demanding environments with configuration available for 120 and 240VAC, single-phase applications.
