## Description

They are DC for accurate measurement of direct current up to 50A, with a standard drop of 75mV for easy reading with compatible ammeters. Robust painted metal construction with plastic insulation, exposed connections for quick mounting and safe contact. Suitable for electrical panels, DC sources, industrial applications and hobby projects.
They are DC 50A with a voltage drop of 75mV, able to accurately and reliably measure current up to 50A in DC electrical systems. It is made of painted metal, with exposed connecting elements, which combines durability with performance, being ideal for a wide range of industrial, commercial and hobby applications.
Using a compatible ammeter to read the voltage drop across the shunt, the current can be calculated using the relationship I = V/R, where V is the voltage drop and R is the resistance of the shunt.
Specifications:
