www.schurter.com86 POWER ENTRY MODULES / GERÄTESTECKER-KOMBIELEMENTE KPS Power entry module Type KPS “Backpack” surge protector to type KP01 Characteristics The overvoltage protection element diverts overvoltages to the earth potential, which are conductively, inductively or capacitively introduced onto the mains. The voltage limitation is effected within nanoseconds through an inert gas divertor and two varistors. The circuit is reversible and after diverting an overvoltage reassumes the high-ohm condition. An inadmissible heating up is prevented by two thermal links. A signal for indication of the failure can be obtained at terminals A1 and A2.
