Enphase Consumption Clamp Current Transformer CT-200-CLAMP

Enphase Consumption Clamp Current Transformer CT-200-CLAMP
The Enphase CT-200-Clamp is a high-accuracy current transformer designed for use with the Enphase IQ Gateway to enable consumption monitoring in residential and light commercial solar systems. With a 200A rating and <1% error, it is ideal for service entrance monitoring in a variety of environmental conditions.
Key Benefits
High Accuracy: Delivers better than 1% metering precision for energy monitoring and reporting.
Clamp-On Design: Easily installs around main supply lines with a secure locking mechanism.
Flexible Application: Rated for Pollution Degree 3 environments—suitable for residential and harsh conditions.
UL Certified: UL2808 compliant with service entrance rating and RoHS certification.
Clear Labeling: Arrows indicate correct current direction for accurate measurements.
Special Technology
Phase-Matched: Designed to be paired with voltage inputs for L1 and L2 for correct power readings.
Parallel Support: Can be parallel-wired to support larger systems or complex service panels.
Multi-Wire Capable: Monitors multiple conductors on the same phase if they fit through the aperture.
Warranty
Backed by standard Enphase limited accessory warranty.
Best Uses
Residential Solar Systems: Enables consumption monitoring via IQ Gateway or Envoy.
Service Entrance Monitoring: Suitable for utility or whole-home monitoring at the main panel.
Multi-Conductor Panels: Can support bundled wires or parallel CT configurations.
