    Choosing a DC ammeter shunt

    Select a shunt by matching its current rating and millivolt output to the meter or monitoring system. Also confirm the mounting style, continuous-current requirements, allowable temperature rise, connection arrangement, and installation environment. Canadian Shunt Industries offers a broad range of standard designs as well as custom configurations for specialized DC power systems.

    Accurate current measurement starts with the right shunt

    Common Ground Marine can help match shunt amperage, millivolt output, mounting, and conductor requirements for marine battery, charging, distribution, and monitoring applications.

    • Match the shunt output to the meter input
    • Size for continuous current and installation conditions
    • Use appropriately sized conductors and sense wiring

    Frequently asked questions

    What does Canadian Shunt Industries manufacture?

    Canadian Shunt Industries manufactures DC ammeter shunts, telecom power fused disconnects, and isolation knife switches. The company states that it offers approximately 300 standard shunt models plus custom designs.

    What is a DC ammeter shunt?

    A DC ammeter shunt is a precision, low-resistance device that produces a small, proportional millivolt signal as current passes through it. A compatible meter or monitoring system uses that signal to calculate current.

    How do I choose the correct shunt?

    Match the shunt's amperage rating and millivolt output to the connected meter or monitor. Mounting style, continuous load, temperature, conductor size, and the required accuracy should also be verified before installation.

    Where are Canadian Shunt Industries products made?

    Canadian Shunt Industries states that its products are manufactured in Canada and designed to ISO quality standards.
