The Simpson Electric Co. 50‑MV Portable Electrical Shunt is an external, portable 50 mV shunt rated for DC currents up to 25 A, designed to be inserted in series with a load so a low‑voltage panel meter can read the current. At 25 A, the shunt drops 50 mV, a value fed into the meter’s inputs, with the meter’s scale adjustability enabling the display to indicate the actual current (for example, using a Mini‑Max M235 200 mV meter paired with the 25 A/50 mV shunt to read 25.0 A). Each portable shunt includes 5 ft leads and is cataloged for 25 A/50 mV operation (Cat. No. 06707 in Simpson’s portable shunt lineup).
