Functional Devices RIBXGF Sensor

Install the Functional Devices RIBXGF split-core current sensor for reliable, non-intrusive monitoring of AC loads in commercial HVACR and building automation systems. Designed for veterans in the field, this split-core fixed current switch features a self-powered design that eliminates the need for an external power supply, simplifying your installs in tight control panels. The RIBXGF current sensor handles a wide sensing range from 0.35 to 150 Amps, making it a versatile choice for monitoring everything from small exhaust fans to large compressor motors. Its Normally Open (N/O) solid-state output triggers once the current exceeds the fixed .35 Amp trip point, providing a clean go/no-go status signal to your DDC controller or PLC. With 16-inch 18 AWG wire leads and a rugged, plenum-rated housing, this unit is built to withstand demanding mechanical room environments. The integrated ratcheting cam clamp ensures a secure lock on the monitored conductor, preventing drift and ensuring consistent current sensing performance across your entire facility.

• Split-Core Design: Allows for easy installation over existing wiring without disconnecting conductors or interrupting equipment operation.
• Self-Powered Operation: Draws power directly from the induced current of the monitored line, reducing wiring complexity and potential failure points.
• Low Trip Point: Fixed .35 Amp threshold provides sensitive detection for low-load status monitoring applications.
• Compact Enclosure: Small form factor and removable mounting tab facilitate clean mounting in crowded electrical cabinets and motor starter boxes.
• Durable Construction: Rated for temperatures from -30 to 140°F and UL listed for safety and code compliance in industrial settings.

How do I install the RIBXGF on an existing motor lead?
The split-core housing snaps directly around the insulated load wire. Use the integrated ratcheting clamp to secure it. Since it is self-powered, you only need to connect the two yellow/white leads to your digital input on the controller.

Will this sensor work with Variable Frequency Drives (VFDs)?
This fixed trip current switch is generally used on the line side of a VFD or on constant-speed motors. For monitoring the output side of a VFD where frequency varies, verify that the minimum current remains above the 0.35A threshold for consistent contact closure.

What is the maximum voltage this sensor can handle?
The Functional Devices RIBXGF is rated for a maximum sense voltage of 600 Vac, making it compatible with most standard 208V, 240V, and 480V industrial power systems.
