Blue Sea Systems 8255 Current Shunt 500 Amp 50mV DC

The Blue Sea Systems 8255 is a precision current shunt designed to work with digital ammeters and multimeters capable of reading up to 500 amperes. This resistive shunt uses a manganin metal element to provide accurate amperage measurements by converting high current flow into a proportional 50 millivolt signal that digital meters can read.

Key Features:

• 500A DC capacity with 50mV DC output ratio for precise current measurement
• Manganin resistive element ensures stable, accurate readings across temperature ranges
• Rated for continuous operation at 66% of capacity (330A continuous)
• Handles intermittent loads up to 300% for 3 seconds, 100% for 5 seconds
• Heavy-duty terminal bolts and screws for secure connections and accurate readings
• Compatible with digital ammeters, multimeters, and battery monitors
• Backed by Blue Sea Systems lifetime warranty

Essential for monitoring battery banks, charging systems, and high-current DC circuits in marine, RV, and off-grid power applications. The robust construction and large terminals ensure proper torque application and long-term reliability in demanding electrical systems.
