Product Details

The Blue Sea Systems 8073BSS is an AC current sensing coil designed for use with AC analog ammeters to provide accurate current measurement in marine and industrial electrical systems. This current transformer allows you to safely monitor AC current without direct connection to high-current conductors.

Key Specifications:

  • Current ratio: 50 Amps AC primary / 50 Milliamps AC secondary (1000:1 ratio)
  • Inside diameter: 0.6 inches - accommodates wire or bus bar pass-through
  • Outside diameter: 1.38 inches - compact footprint for tight installations
  • Includes connection cable for easy ammeter integration
  • Compatible with Blue Sea Systems AC analog ammeters and other 50mA meters

How It Works:

The sensing coil installs around the current-carrying conductor without breaking the circuit. As AC current flows through the conductor, the coil generates a proportional milliamp output signal that drives your analog ammeter. This provides a safe, isolated method of current measurement in shore power systems, generators, and AC distribution panels.

Applications:

Ideal for monitoring AC loads on boats, RVs, and backup power systems. The 0.6-inch inner diameter accommodates most standard wire gauges and small bus bars, making it suitable for circuits up to 50 amps.
