Overload Relay Switch is used as electrical switch in industrial setting to protect electrical equipment from damage due to overheating in turn caused by excessive current flow. The Overload Relay Switch is provided for protecting components connected to an electrical circuit in the event the current flowing through the circuit exceeds a predetermined level. The Overload Relay Switch monitors the current flowing in the protected circuit and sends a signal to cause a contactor in the protected circuit to open when the current flowing in the protected circuit is higher than a pre-selected level.
Overload Relay Switch is manufactured by Apple Automation & Sensor. Apple Automation & Sensor also manufactures a wide range of industrial process instruments that include proximity sensor, optical sensor, relay card, special sensor, flow switch, tower lamp, power supply, panel accessories and relay.
