Blue Sea 9230 Analog Meter Shunt 100A/50mV [9230]

This Blue Sea Systems shunt uses a 100A/50mV rating for connection with DC ammeters. A shunt creates a small, measurable voltage drop that the meter uses to indicate current without routing the full load through the meter. Separate sense connections support accurate readings when properly installed, while the manufacturer recommends limiting continuous operation to 66% of the rated current under normal conditions.

• 100A/50mV rating: Matches compatible 50mV DC ammeters for current monitoring.
• Designed for DC ammeters: Supports electrical measurement in marine, RV, and other DC systems.
• Low-resistance sensing: Produces a small voltage signal for the connected meter while minimizing circuit voltage loss.
• Dedicated sense connections: Helps maintain measurement accuracy when sense leads are installed correctly.
• Continuous-use guidance: Operating at no more than 66% of the rated current under normal conditions helps keep the shunt within recommended use parameters.

• What does the 9230 measure?
  It provides a 50mV sensing signal for monitoring DC current with a compatible analog ammeter.
• What is the shunt’s rated capacity?
  The shunt is rated for 100A.
• What meter is compatible with this shunt?
  Use it with a DC ammeter designed for a 50mV shunt input.
• Can it be used continuously at 100A?
  Blue Sea Systems recommends limiting continuous operation under normal conditions to no more than 66% of the rated current.
• Are the sense connections part of the main current path?
  No. The separate sense connections are intended for measurement leads and should not be used as current-carrying connections.
