Shunt used in d-c power circuit for metering also serves here to drive base of transistor that senses over-loads. Relay in transistor circuit disconnects d-c power when drop ccross 100-mv shunt approaches 400 mv (4 times normal load current).-J. J. Pirch, Single-Transistor Short-Circuit Detector, EEE, 12:16, p 64.
