The RIBXKTF, by Functional Devices, is a solid-core current switch.
It connects (closes) a circuit when a current threshold of 500 mA or higher is detected on the primary conductor. The RIBXKTF is useful for understanding whether or not a device has been turned or not, or if a device is drawing more current than it should be. The RIBXKTF can help determine if maintenance is needed.
The RIBXKTF is UL Listed and manufactured in the USA.
