TP CHNGERS TYPE EHR GENER SPECIFICTION These tap changers are available in one, two or three phase applications. Multi layer types are also available. The shaft length is fixed as 0, 0, or 10mm. Driving mechanism can be either on the edge or in the middle the phases. Connection diagrams in page EHR 2 can be applied in any variation to all types. Easy assembly and compact desing provides labor and cost savings. CURRENT CURRENT 10 0 CONTCT INNER DI. (For cable connection) ø 2.1 mm. ø.1 mm. ø.1 mm. SSEMBY notch is provided to mark each position. For operation, unscrew and release the notch by applying an axial pull on the control knob. Then turn the knob to the desired position. Engage the knob and screw the lock nut. This process is clearly marked on control knob as; " I IFT II TURN III SWITCH ON " This description can be engraved in any language.
