Transport Installation Use
Despatch
Make sure that the contact is in opened position
before packaging and transporting.
While transporting the contactor can not be
reversed, intense shocked and collided.
Installation
The contactor must be installed on a level, and the
gradient mustn’t be over 5 .
Make sure that the electric connection is right,and
the control voltage is equivalent to the contactor’s
Use
The value of contact travel can be found in technical
data. The way of measure as it is: First, measure
the distance ‘h’from flexible connection to the face
of the carapace on the closed state, and then in

"JCZ5-7.2,12"型号的高压真空接触器是一种专门用于交流高压电力系统中的开关电器。其中，“JCZ5”通常代表该产品的系列号或厂家代码，“7.2”指的是额定电流，即在正常工作条件下允许通过的最大持续电流，单位为千安（kA），这里是7.2kA。而“12”则表示额定电压，即设备能够安全操作的最高工频交流电压有效值，单位为千伏（kV），这里为12kV。 因此，这款高压真空接触器适用于12kV等级的电力系统中，作为主开关或保护用，能够在短路、过载和欠压等情况下可靠切断或接通电路，因其采用真空灭弧技术，具有体积小、重量轻、寿命长、维护方便以及无触头电弧等特点，被广泛应用于电力牵引、发电厂、变电站、输配电等领域。
