Datenblatt Jecotec Shunts / Nebenwiderstände


A shunt, also known as a shunt or shunt resistor, is originally an electrically conductive device that is connected in parallel to a part of a circuit to dissipation an electrical current from that part.

The term shunt has evolved and also refers to a current measuring resistor, which is a low-impedance electrical measuring resistor, often equipped with separate current and voltage terminals. This is inserted directly into the live line. Due to the voltage meter connected in parallel to this type of shunt, only a mostly negligibly small current is derived.

For large currents, guideline value greater than 10 A, the current measurement is usually carried out by measuring the electrical voltage on a shunt with a voltage measuring device. These shunts are often designed for a voltage of 60 mV or 150 mV at the nominal value of the current. The current in the shunt is calculated according to Ohm's law (source Wikipedia).
