General Electric, a pioneer in the development of the Surge Protection Device, maintains a large and robust lineup of Surge Protection Devices. The SPD, formerly known as TVSS, is applied to many locations in the power distribution system. G.E. utilizes a best in industry sized MOV to provides surge ratings up to 300kA/mode. The units have been independently tested up 20,000 C3 surges with less than a 10% change in voltage clamping performance in both wall mount and integral designs. A din rail product rounds out the portfolio with the ability to provide up to 50kA surge rating on control bus applications. This is perfect for PLC, controls, and telecomm protection.
