Product Specifications
Brand: Siemens
Part Number: 3NJ6930-3DB00
Product Type: Current Transformer Busbar
Series: SENTRON 3NJ693
Suitable For: Switch disconnector with fuses, in-line design, NH1
Number of CT Positions: 1
Rated Operational Voltage: 690 V AC / 440 V DC
Standard: IEC EN 60947-3
Product Description
The 3NJ6930-3DB00 is a CT busbar assembly for mounting a single bushing current transformer onto a SENTRON 3NJ6 (NH1) in-line switch disconnector with fuses. Designed for the larger NH1 frame size, which accommodates higher current ratings than the NH00 series.
NH1 Frame — Higher Current Capacity
The NH1 frame supports larger fuse links and higher continuous currents than NH00. This single-position busbar assembly provides the primary conductor path through a single CT window, enabling current measurement on one phase of an NH1-rated feeder.

Retrofittable Design
All 3NJ6930 series busbar assemblies can be retrofitted at any time — no need to disconnect the main circuit or remove the switch disconnector from the panel. The plug-in interface ensures quick installation without tools, letting panel builders add metering capability as requirements evolve.
