Product Description

The 3NJ6930-3DC00 is a CT busbar assembly for mounting three bushing current transformers onto a SENTRON 3NJ6 (NH1) in-line switch disconnector with fuses. Designed for the larger NH1 frame size with three CT positions for complete three-phase monitoring on higher-current feeders.

NH1 Frame — Higher Current Capacity

The NH1 frame supports larger fuse links and higher continuous currents than NH00. This three-position busbar assembly enables full three-phase current measurement on NH1-rated feeders, with each position accepting a standard bushing-type CT.
