とする逆相防止リレー。 A case where a three-phase power supply includes a resistor, a capacitor, and a control relay, and the resistor, capacitor, and control relay coil each form each phase of a three-phase star circuit, and the three-phase power supply rotates in phase in the order of the resistor, capacitor, and control relay coil. In the reverse phase prevention relay in which the control relay operates by applying a voltage to the relay coil that enables driving of the electric contacts driven by the coil, the control relay is connected to a power terminal to which the three-phase power source is connected. The resistor and capacitor are housed in a case equipped with an output terminal that draws out the electrical contact of the control relay to the outside, and the control relay blinks via the electrical contact that is driven by the control relay coil. What is claimed is: 1. A reverse phase prevention relay comprising: a reverse phase prevention relay, and configured to be detachably attached to the case.
