Analog meter shunt for DC ammeters, providing a 50A/50mV measurement reference for marine electrical monitoring.

The Blue Sea Systems 9228 converts current flow into a proportional millivolt signal for compatible DC ammeters. Its 50A DC/50mV DC ratio supports current monitoring in boating and other 12V or 24V DC electrical systems. The resistive Manganin metal element provides the sensing path, while the compact 0.20 lb construction suits panel and equipment installations. For continuous operation, Blue Sea recommends limiting normal current to 66% of the rated capacity.

  • 50A DC/50mV DC ratio provides a compatible signal for DC ammeters.
  • Designed for use with analog DC ammeter systems to monitor electrical current.
  • Resistive Manganin metal element delivers the shunt’s current-sensing function.
  • 66% continuous-duty recommendation helps keep normal operating current within the manufacturer’s guidance.
  • Supports compatible Blue Sea meter systems, including 0–50A and 50–0–50A configurations.
  • Weighs 0.20 lb (0.09 kg), helping simplify installation in marine electrical panels.
The 9228 is installed in a DC electrical circuit and used with a compatible ammeter that reads the shunt’s 50mV output. This arrangement lets the meter display current without placing the full circuit load through the meter itself, making it suitable for marine power monitoring and other DC systems.
Use it when replacing a matching 50A/50mV shunt or assembling a compatible Blue Sea analog ammeter installation. The shunt is associated with Blue Sea Systems DC meters such as the 8041, 8022, and 8252 configurations. During setup, follow the meter and system wiring instructions and size the installation for the intended current. For continuous operation, keep normal current at or below the stated 66% recommendation; the published intermittent rating is 100% for five minutes or 300% for three seconds.
