Product Details

AC high voltage vacuum contactor with fuse composite apparatus

JCZ33 series AC high voltage vacuum contactor is suitable for the AC power system, with rated voltage 12kV, rated frequency 50/60 Hz and rated current 50A-630A, of which need amount of opening and breaking operation cycle and as the ideal electric apparatus for frequent operation. JCZR2 series AC vacuum contactor-fuse composite apparatus based on JCZ33 series AC high voltage vacuum contactor add the high voltage current-limiting as short circuit protection,expand the usable fields and make the design of main circuit easier.

JCZ33 series AC high voltage vacuum contactor mainly consists of vacuum tube, operating mechanism, control electro-magnet, power model and other auxiliary components, housed in the space from the top frame poured completely by resin to the low frame made by steel. The control electro-magnet complete the closing action of the contactor by way of operating mechanism, while the opening action completed by the opening spring. The composite structure ensure it's long electric and mechanical life without frequent maintenance.
