This is an external current transformer for neutral conductors (ENCT) for ComPact NSX100-250 with Micrologic 5/6 trip units. For three-pole devices, the distributed neutral conductor of the system can be protected by installing this external sensor. The rated current of the sensor ranges from 25 A to 100 A. The ENCT must be connected to the Micrologic trip unit via a shielded twisted pair cable. The maximum cable length is 10 m and the cross-section must be between 0.4 mm² and 1.5 mm².
