The laboratory shunt resistor from Chauvin Arnoux is a measurement accessory specifically developed for measuring high direct currents (DC), to be used in combination with a voltmeter. The device converts a current flow into a measurable voltage, allowing the current value to be calculated based on the voltage across the resistor. It is designed for use in laboratory and testing environments where high safety standards and precise measurement results are required.

Applications
This shunt resistor is suitable for professional use in laboratories, testing, and demanding test environments. It enables the measurement of high direct currents, with the exact current value determined by measuring the voltage at the terminals. Use in educational institutions is also possible, particularly in teaching series, where double-insulated connections and secure terminals are required.

Functions and Features in Detail
The device features protective insulation in accordance with IEC 61010, Category CAT III 600 V, ensuring high safety when working with electrical voltages. The safety sockets with a diameter of 4 mm allow for easy and secure connection with test leads. The housing is impact-resistant and self-extinguishing, increasing safety in demanding environments. The accuracy class of 0.5 ensures reliable measurement results, and the very low temperature coefficient minimizes measurement deviations under varying ambient temperatures.

Technology Explained Simply
A shunt resistor, also known as a shunt, operates according to Ohm’s Law: the current flowing through the resistor generates a voltage proportional to the current. This voltage is measured with a voltmeter, and the current is calculated from the ratio of voltage to resistance value. The double insulation and safety sockets protect the user from electrical hazards. The CAT III 600 V category means the device is suitable for measurements in electrical installations with a nominal voltage up to 600 V, under normal operating conditions.

Compatibility and Accessories
The shunt resistor is designed for use with a voltmeter. The terminals are designed for banana plugs with a diameter of 4 mm. The product range includes various rated currents, including 1 A, 5 A, 10 A, 20 A, and 30 A, with the current item rated for 5 A. The double-insulated connection makes it particularly suitable for use in educational institutions and laboratories.

Installation and Mounting
Installation is carried out by directly connecting the safety sockets to the corresponding test leads. No additional mounting or installation is required. The robust construction ensures a secure and stable connection without additional holders or fastening elements.

Operational Advantages
The laboratory shunt resistor offers high measurement accuracy due to its accuracy class of 0.5 and minimal temperature dependence. The safety sockets and double insulation increase operational safety. The impact-resistant and self-extinguishing housing protects the device from mechanical stress and in the event of a short circuit. The combination of safety, robustness, and precision makes this device a reliable tool for professional measurement tasks.
