100A DC Ammeter Shunt ResistorRated Current: 100AVoltage Drop: 75mVMaterials: CopperOverload Rated Current: 120%(2 Hours)Accuracy: 0.5%Working Temp: -40C to 60C(-40F to 140F)Type: FL-2 ExternalLength: 105mmWidth: 22mmOverall Height: 26mmWeight: 139g Application: An ammeter shunt allows the measurement of current values too large to be directly measured by a particular ammeter. In this case, a separate shunt, a resistor of very low but accurately known resistance, is placed in parallel with a voltmeter, so that all of the current to be measured will flow through the shunt.
