Bolt-on DC Shunt Resistor for Current Sensing

Description

Ultimate 100A Bolt-on DC Shunt Resistor for Accurate Current Sensing

A bolt-on DC shunt resistor is a precision current sensing component designed to convert high DC current into a measurable 75mV voltage drop for accurate monitoring in industrial and energy metering systems.

Our industrial meter shunt resistors provide precise and reliable DC current measurement solutions for various industrial applications. Designed with high thermal stability and low tolerance, these shunts ensure accurate readings in harsh environments, making them suitable for energy meters, current monitoring systems, and industrial automation devices.

Constructed from high-quality alloy materials, our shunt resistors feature excellent linearity, low temperature coefficient, and superior long-term stability. Available in a wide range of resistance values, they can handle currents from a few milliamps up to several hundred amperes, making them adaptable to different measurement requirements.

Precautions

Do not touch the primary circuit conductors or the connection points of the shunt while in operation to avoid electric shock.
Do not draw any signal or take samples from the secondary circuit.
This DC Shunt Resistor is designed for DC measurement circuits with a rated insulation barrier voltage of 275 V.
When used together with a 75 mV current-limited moving-coil (magnetoelectric) ammeter, it effectively extends the ammeter’s current measurement range.

For more detailed safety standards, you can refer to IEC 61010-1 Safety Requirements for Electrical Equipment.
