The SPDT Relay (30 A) is a high quality Single Pole Double Throw Relay (SPDT).The Relay consist 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 5 V and the contact is rated up to 30 A (@ 250 V AC, 30 V DC). Use it to control AC appliances or high current DC devices.
