06-Shunts

Product catalog summary

Application: Shunts are essential accessories for measuring current in DC installations, particularly for high amperages. They provide a measurable voltage drop proportional to the current, suitable for use with moving-coil ammeters and wattmeters. Standard voltage drops are 60 mV and 150 mV, with 150 mV recommended for high voltage drop scenarios.

Operating Principle: Shunts consist of high-accuracy manganin resistance elements, ensuring a steady voltage drop due to their low temperature coefficient. They are available in accuracy classes 0.5 and 0.2 (special executions on request) and can be mounted on a 35 mm DIN rail.

Technical Data: Shunts comply with electromagnetic compatibility standards EN 61000-6-2 and EN 61000-6-4. They can handle continuous overloads of 1.2 times the rated current and short-term overloads up to 5 times the rated current. The operating temperature range is -10 to +55°C, with storage temperatures from -25 to +65°C. They are suitable for climates as per VDE/VDI 3540 and have a relative humidity tolerance of ≤ 75% annually.

Dimensions and Versions: The document provides detailed dimensions and specifications for shunts with 60 mV, 100 mV, and 150 mV voltage drops, including weight, bolt sizes, and terminal configurations for various current ratings.

Catalog excerpts

SHUNTS APPLICATION Shunts are indispensable accesories for measuring current in DC installations, specially for high amperages. They provide a voltage drop (mV) proportional to the current, which is easily measurable by means of moving-coil ammeters (types PQ y PAQ). They can also be connected to wattmeters (type DQ../1w) and other measuring devices. Standard voltages drops are 60 mV and 150 mV. Shunts of 150 mV are recommended when the voltage drop across the potential leads is high, due to their length and/or the high consumption of the instrument. The best performance is guaranteed if the...
