Crestron GLS-EM-CT-20A

The GLS-EM-CT is a current transformer designed for use with a GLS-EM-MCU Crestron Green Light Power Meter Control Unit[1]. Current transformers are vital to metering power. Crestron offers various split core models that work with 600, 400, and 200 Amp feeds; these devices clamp around main feeds. Solid core models exist for 50 and 20 Amp circuits; the wire must be routed through the closed loop of the core.
