Westinghouse Brass Electrical Shunt 150A 75mV Antique Industrial 1920
This is an original Westinghouse brass electrical current shunt, an early industrial electrical measuring component used with analog ammeters in power and industrial applications. Constructed with heavy copper/brass terminals on a phenolic base, this piece exemplifies early 20th-century electrical engineering.
The shunt is clearly marked WESTINGHOUSE and 150 / 75, indicating a 150-amp, 75 millivolt rating—a standard specification for industrial ammeter shunts of the era. The cloth-insulated leads and robust brass hardware further support an early 1900s manufacture. A scarce and desirable piece for collectors of antique electrical equipment, industrial décor, or museum display.
