Blue Sea 8255 Digital Meter Shunt - 500A/50mV

The Blue Sea 8255 Digital Meter Shunt is a 500A/50mV shunt built for use with DC ammeters that need an external current-sensing shunt. It is designed for boaters and installers setting up or replacing a shunt for a digital DC ammeter installation, including Blue Sea's own digital multimeters.

For continuous operation, Blue Sea recommends running the shunt at no more than two-thirds (66%) of its rated current under normal conditions, which keeps it well within its safe operating margin over the long term. It's the standard shunt referenced by Blue Sea's Shunt Shifter adapter for positive-side installations. Browse more options in our panels, switches, and circuit breakers category.
