Product Details

The Blue Sea Systems 8257BSS is an AC current sensing coil designed for use with AC analog ammeters to provide accurate current measurement in marine and electrical systems. This current transformer converts high amperage AC current into a proportional low-level signal that can be safely read by standard analog meters.

Key Features:

  • 100 amp AC to 50 milliamp AC current transformation ratio (100:1)
  • Compact design with 0.6 inch inside diameter and 1.38 inch outside diameter
  • Includes pre-attached cable for easy connection to analog ammeters
  • Split-core or solid-core design allows installation without disconnecting existing wiring
  • Suitable for monitoring AC shore power, generators, and inverter output
  • Marine-grade construction for reliable performance in harsh environments

This current sensing coil is ideal for retrofitting existing electrical panels or installing new AC monitoring systems. The 0.6 inch inner diameter accommodates most standard wire sizes, while the included cable simplifies integration with compatible Blue Sea Systems ammeters and other monitoring devices.
