- voltage drops: 50mV,
- accuracy class:
- 0.2 for measuring range ≤ 2500 A
- 0.5 for measuring range > 2500 A
- catch clamping on a rail or to the base.
- external dimensions: depending on the execution.
Measuring shunts B4 type are destined to extend measuring ranges of d.c. ammeters, wattmeters and electrodynamic or ferrodynamic counters which accuracy classes are: 0.5; 1; 1.5; 2.5.
