This Eaton D3PF2AA general purpose, ice cube-type relay receives and controls electric signals in power supply applications. It has double–pole, double-throw (DPDT) Form C contacts and is capable of breaking relatively large load currents. It has an 8-pin plug-in terminal for a socket connection. This relay has an AC coil with a rating of 120 VAC, resistance of 1.7 kohm, and a contact current of 12 amp. It has a built-in LED indicator to alert users to the operating status and a flag indicator to check the status in either manual or powered mode. It has a push-to-test button for manual operation without the need for coil power, and it has a plastic nameplate for labeling. This general purpose relay is suitable for use in HVAC, appliance, and automation applications, among others.

Relay switches (also called an electrical relay or an electrical relay switch) use a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch, it moves through the coil and a magnetic field is created, which causes the lever in the load circuit to move between contacts, either turning the device on or off. In a normally open (NO) relay switch, when power is supplied to the relay, the load circuit is closed and the power source connected to the relay is turned on. In a normally closed (NC) relay switch, when power is supplied to the relay, the load circuit is open and the power source connected to the relay is turned off. In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system.
Eaton manufactures electrical, hydraulic, and mechanical power equipment. The company, founded in 1911, is headquartered in Dublin, Ireland.

This is your standard ice-cube type relay but beware, the photo shows the socket (the gray part) that the relay plugs in to but it is not included with the relay.
