Arco Starting & Charging ST500 500A/50mV Marine Shunt

The Arco Starting & Charging ST500 is a precision current measuring shunt designed for marine electrical systems. This heavy-duty shunt provides accurate current monitoring by producing a 50 millivolt output at 500 amps of current flow, making it ideal for use with digital amp meters, battery monitors, and marine electrical management systems.

Key Features:

• 500 amp continuous current rating for high-capacity marine applications
• 50mV output voltage provides precise current measurement
• Corrosion-resistant construction suitable for harsh marine environments
• Compatible with most digital amp meters and battery monitoring systems
• Essential component for monitoring battery charge and discharge rates

This current shunt is installed in series with the electrical circuit being monitored, typically in the negative battery cable. The 50mV voltage drop across the shunt is proportional to the current flow, allowing connected meters to accurately display amperage. Ideal for sailboats, powerboats, and marine applications requiring precise electrical system monitoring.
