The OPTOEMU-ACT-1250-400 split-core current transformer (CT) from Continental Control Systems offers an easy, safe, and inexpensive method for monitoring electrical energy usage.

Ideal for retrofit applications, the split core makes it possible to attach the CT without disturbing existing wiring. This CT swings open for one-handed operation. Just open it, slip it over the wire, and snap the CT closed. Once assembled, the CT has no exposed metal parts.

The 0.333 VAC output of this CT is low, making it much more safe to install and use than CTs with current secondaries. It is also less expensive.

ACT series CTs comply with the linearity and accuracy requirements of IEEE/ANSI C57.13 class 1.2 for tenant submetering and billing. They are UL Listed, certified by Underwriters Laboratory (UL) to meet the new 2017 NEC code requirement that CTs installed in the field must be UL 2808 Listed under category code XOBA.

This CT is recommended for use with the following Opto 22 products:
  • groov EPIC® power monitoring analog input module, part number GRV-IVAPM-3
  • groov RIO® energy monitoring edge I/O module, part number GRV-R7-I1VAPM-3
  • SNAP power monitoring analog input module, part number SNAP-AIPM-3V 
  • OptoEMU Sensor„¢ power monitoring appliance, part number OPTOEMU-SNR-3V 
Determine the maximum current you need to measure and choose a CT with a primary current that handles both wire size and maximum current. Other CTs available:
  • OPTOEMU-ACT-0750-050
  • OPTOEMU-ACT-0750-100
  • OPTOEMU-ACT-0750-250
  • OPTOEMU-ACT-1250-250
  • OPTOEMU-ACT-1250-600
NOTE: The OPTOEMU-ACT-1250-400 can be used as a drop-in replacement for the obsolete OPTOEMU-CTS-1250-400.
