The invention discloses a starting protection relay. The starting protection relay comprises a constant current input circuit module, a time-delay circuit module, an isolating circuit module, a driving circuit module and an output module which are electrically connected in turn; the time-delay circuit module comprises an RC (Resistor-Capacitor) circuit, a diode and a negation gate; the isolating circuit module comprises an oscillating circuit and a transformer which is coupled to the oscillating circuit; the driving circuit module comprises a field effect tube, an overheat protector and a first RCD (Residual Current Device) circuit; the field effect tube is an insulated gate field effect tube namely an MOSFET (Metal Oxide Semiconductor Field Effect Transistor); the output circuit module comprises a second RCD circuit; the output end of the second RCD circuit is electrically connected with a starter. The starting protection relay can effectively protect the starter by limiting a single starting time.
