简单介绍

SCT是一个与电流传感器集成的分芯电流互感器，可提供高达500Aac的电流测量范围。可提供0-1mAdc、0-5Vdc或环路供电的4-20mAdc输出。输出与输入的平均绝对值成比例，并经过校准以表示正弦波的RMS值。

The SCT is a split-core current transformer integrated with a current transducer to provide current measurement ranges up to 500Aac. Outputs of 0-1mAdc, 0-5Vdc, or loop-powered 4-20mAdc are available.The output is proportional to the average absolute value of the input and is calibrated to represent the RMS value of a sine wave.

安装说明/INSTALLATION INSTRUCTIONS

1.只能由合格的电工进行安装！

2.在进行任何电气连接之前，确保电气服务已断开。

3.支路保护按国家和地方规范要求设置检查机构的报告。

4.按要求布线，并按照本表和装置上的接线图固定到端子上。

5.传感器适合安装在600Vac线路上。

6.为防止与带电电路接触，当安装在裸母线上时，要求传感器安装在需要使用工具进入的外壳中。当安装在绝缘电缆上时不需要第二个外壳的电缆。

1. Installation should be performed by qualifi ed electricians only!

2. Make sure electrical service is disconnected before making any electrical connections.

3. Branch circuit protection is required to be provided in accordance with the National and Local codes of the inspection authority.

4. Route wires as required and secure to terminals per connection diagram on this sheet and on the unit.

5. Transducers are suitable for installation on 600Vac lines.

6. To prevent contact with live circuits, when installed on a bare bus bar, the transducer is required to be mounted in an enclosure that requires the use of a tool for access. When installed on an insulated cable this second enclosure is not required.
