The surge protection devices (SPDs) protect systems and electrical devices against excessively high voltage peaks caused by switching operations and lightning strikes. Without surge suppressor built in, the surges can damage the circuit easily due to overload, interrupt processes and causing the electronics to prematurely age. The structure of the Kingfont PowerSpeed™ power connectors was designed to address the need for super high amperes, combining with Kingfont’s surge protection device can prevent damage by impulse currents.
