Model 4NO4 (Split) | 4NOC (Solid) | IP68 Rated Current Transformer

Models: 4NO4 | 4NOC


The Models 4NO4 (Split Core) and 4NOC (Solid Core) are IP68 rated outdoor Current Transformers. These CTs are designed for ground fault monitoring and provide either a voltage or milliamp output. The volt output can be any voltage from 50mV to 1VAC and the milliamp version can be up to 333mA. The 4NO4 version is meant to be installed around conductors that are at ground potential. The 4NOC version is available for above ground potential installations. In either case, the 4NO4 Series can be completely submerged. The 4NO4 split core version has been tested submerged down to 15 feet. The unit uses corrosion proof magnetic core material and is encapsulated except for the removable top bar on the split-core version. For an outdoor Instrument Current Transformer with 1A or 5A output, refer to the model 5NO5.
