More Info
The Enphase CT-200-Clamp is engineered for high-accuracy current measurement in residential and light commercial solar installations.
Its clamp-on design with a secure locking mechanism enables quick and safe installation around main supply conductors without disconnecting wiring.
Rated for Pollution Degree 3, this current transformer performs reliably in both residential and harsher industrial environments.
UL2808 certification and RoHS compliance ensure the product meets stringent safety and environmental standards.
Phase-matched design allows pairing with voltage inputs for accurate L1 and L2 power readings.
The CT supports parallel wiring configurations, enabling monitoring of larger or more complex electrical service panels.
Multiple conductors on the same phase can be monitored simultaneously if they fit within the aperture diameter.
Operating temperature range from -40°F to 185°F (-40°C to 85°C) and up to 95% non-condensing humidity rating ensure durability in varied conditions.
Enphase Energy is a global leader in solar technology, known for microinverters and integrated energy management solutions.
