The SPDT Relay(30A) consists of a coil, 1 common terminal, 1 normally closed(NC) terminal and one normally open(NO) terminal.When the coil of the relay is at rest (not energized), the common terminal and the normally closed terminal have continuity. When the coil is energized, the common terminal and the normally open terminal have continuity. This relay's coil is rated up to 5V and the contact is rated up to 30A (@250VAC, 30VDC). This relay can be used to control AC appliances or high current DC devices.



Please exercise great care and safety precautions when working with mains voltages. If in doubt, contact a professional such as a licensed electrician for help.
