ATO-XXX-B333-D10 Split-Core Current Sensor by LEM

Clear
Product Description

The ATO-XX-B333-D10 Split-Core Current Sensor by LEM is a 10mm hinging CT designed to make installation easy.

It has primary ratings from 10A to 75A and outputs a corresponding 333 mV signal.  The opening mechanism on this CT is incredibly easy to use – significantly easier to latch and unlatch than its competitors.

It meets Accuracy Class 1 per IEC 61869-2 and has a slot for attaching the CT on the primary with a plastic tie.  It is UL 508: 2013 compliant.

Applications include:

  • Hybrid inverter (Home energy storage)
  • Power metering: current measurement for active power calculation
  • Building sub-metering: energy efficiency monitoring, consumption analysis and cost allocation
  • Power quality metering: electrical loads and distribution system equipment
  • Distributed measurement systems
  • Condition monitoring, e.g. motor loads such as conveyers, pumps

Compatible power meters accept a voltage input.  Look for meters on our website that start with this symbol:
