Miniature Ring Current Sensors Features
The ND Miniature Ring series of solid-core current sensors are manufactured for use with ND type “V” Meters (Cube 350V, Cube 400V, PowerRail 350V, MultiCube Modular, etc). They offer installation where space is critical —ideal for Energy Management Systems. With a safe low voltage output, there are no worries about open circuiting CT secondary circuits. • Miniature Size • Low Cost • Safe & simple to install
Ring Sensor 20, 40 or 60 Amp
