It's a T-Shape general-purpose Relay 24V DC 30A. Mostly, relays are used to perform switching operation  without manual touch. It is used to control the flow of current. General purpose Relays are primarily used as a control circuit (relay sequence) for automated machinery employed at various industrial sites as well as for other control systems including lighting, air conditioning, and water treatment in buildings.

Applications: 

• Relays are electrically operated switches
• It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. 
• Power relays open or close a circuit by using an electromagnetic coil for seamless power flow. 
• The operating voltage of a relay is generally in DC
