The test rectifier consists of a medium power silicon rectifier mounted on an appropriate heat sink in a small molded case. Connections to the terminals at each end of the case may be made by clamping leads or terminal under the molded thumb nuts, or by clipping the leads directly to the hexagonal portion of the terminal. A half wave rectifier symbol is shown on the nameplate of facilitate proper choice of DC meter connections.

APPLICATION
The test rectifier is a compact, portable piece of test equipment designed for calibration testing of the second harmonic restraint feature of differential or overcurrent relays.
