12VDC 30A Power Relay 4 Pins General Purpose Relay 1 Form A C
30A Power Relay Description:
WRG's RA2-112LM-S power relay, RA2xx is PCB mount, QT 250, 112 is 1 pole, DC12V, L represents coil power 900mW, M points to normally open, S means sealed, so it is 12V30A, 0.9W, SPST-NO, sealed, PCB relay mount and fast terminal 250 are installed together.
What is the difference between a power relay and an electromagnetic relay, and where is the power relay used?
Signal relays are generally used for monitoring and protection, and are often used in secondary protection circuits of power distribution high-voltage cabinets. For example, if the temperature of the transformer oil exceeds 85 degrees, the normally open contact on the temperature monitoring indicator closes. This contact is connected in series in the coil circuit of the signal relay, so the signal makes the coil of the signal relay close, the signal relay operates, the "light" signal drops, and the high-voltage switch is disconnected. At the same time, the load on the transformer will be removed, thus protecting the transformer. But there are many kinds of signal relays, some of which directly send out buzzers or flashing lights as alarm signals. When the secondary protection circuit operates, the signal relay operates. It will tell the relevant personnel exactly which protection is wrong, and its appearance has obvious activation signs. A power relay is a device that can generate jumps in one or more electrical output circuits when the input quantity (or excitation quantity) meets certain specified conditions. It can be used in the direct grounding system of the neutral point as a directional element for zero-sequence current protection.
