Model 5NO5 (Split) | 5NOC (Solid) | IP68 Rated Instrument Current Transformer

Models: 5NO5 | 5NOC

Application Description

The Ground Fault Current Transformers, Models 5NO5 (Split Core) and 5NOC (Solid Core), are outdoor instrument current transformer that provide either 1A or 5A output current. The 5NO5 (Series) Ground Fault Current Transformer is designed for ground fault monitoring/metering of outdoor conductors. The 5NO5 is a split-core version that is meant to be installed around conductors that are at ground potential. The 5NOC is a solid core version which is available for above ground potential installations. In either case, the 5NO5 can be completely submerged. The 5NO5 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. The unit illustrated above is rated at 500A and has a 1A output. The saturation point (“knee”) depends on the external burden provided when ordering. For an outdoor current transformer with millivolt (such as 333.3mV) or milliamp (100mA), please refer to our Models 4NO4 and 4NOC.
