WAGO’s Plug-in Current Transformers with CAGE CLAMP® Connection measure AC currents in 230 V, 400 V and 690 V low-voltage mains. The current transformer can be loaded with up to 120% of the nominal current, allowing you to measure peak currents without damaging the transformer. The current transformers of accuracy Class 1 and Class 3 can be mounted on either round cables or current bars. Plug-in Current transformers are equipped with the vibration-proof and maintenance-free CAGE CLAMP® connection. The output is accessible from two sides, allowing the conductor to be easily terminated even in space-restricted applications.
