Measuring shunts B4 type are destined to extend measuring ranges of d.c. ammeters, wattmeters and electrodynamic or ferrodynamic counters which accuracy classes are: 1, 1.5, or 2.5.
• Extension of d.c. current measuring ranges of moving-coil ammeters.
• Accuracy class 0.5.
• Voltage drops : 50mV
• Shunts of 1…25 A ranges are fixed on an isolating base.
• The isolating base is adapted to be assembled on a 35 mm DIN rail.
• On request, additional chemical coating are available: lackering, silver or nickel plating.
