The Dayton 6C054 is a current sensing relay that is used for a variety of applications. This relay is used to sense the current flowing through an electrical circuit and to close the contacts in response to the current. A current sensing relay can be used in applications such as control of a motor, heater, or appliance. Relays like this one have SPDT (single-pole, double-throw) contacts. The relay is surface mount, and has quick connect tabs for easy wiring.
