Comutator cu came PKP 25-53 O 25AUca-O-Uab-Ubc3P/400V

PKP cam-type position switches of IEK brand are mechanical devices without internal consumption intended for installation as switching units. PKP can be used as main or group switches for controlling drives based on the single-or three-phase motors, switching with the required control circuits commutation program, alarm, measuring circuits etc. They are applied in AC electric circuits with voltage under 400 V.Drive fixation mechanisms guarantee stable switching of moving contacts into separate fixed positions. Drive springs of the fixing mechanism differ depending on the number of commutation elements. Cam mechanism represents a modern solution of manual electric circuit commutation ensuring the following advantages: – Minimum electric voltage of closed contact; – Double break of electric circuit (bridge contact); – High speed of contacts opening and closing provides for more rapid arc extinction; – Ensuring different strengths and handle free travel at switching on/off; – Reaching wider range of commutation circuits when having the same set of details and assembly units that means better unification; – Longer operational life (number of commutations to the full).Number of poles: 3 Max. rated operation voltage Ue AC: 400 Rated permanent current Iu: 25.0 Number of switch positions: 4 Device construction: EV002104 Type of control element: EV000092 Front shield size: IEK_V0000771 Degree of protectio
