Functional Devices RIBX24SBF Current Sensing Relay 20 Amp SPST with Override 24VAC/DC

The Functional Devices RIBX24SBF is a combination current sensing switch and relay designed for HVAC and industrial control applications. This versatile device monitors current flow and provides both automatic switching and manual override capability in a compact NEMA 1 rated enclosure.

Key Features:

• Fixed current sensing range: 0.5 to 20 Amps
• 20 Amp SPST (Single Pole Single Throw) relay output
• 24 VAC/DC control voltage for universal compatibility
• Built-in manual override switch for testing and emergency operation
• NEMA 1 rated housing for indoor applications
• Compact design for easy panel or junction box mounting

This current switch activates the relay when current flow through the monitored circuit reaches the preset threshold, making it ideal for fan proving, pump monitoring, and equipment status indication. The manual override allows operators to bypass the automatic sensing function when needed for maintenance or testing. The RIBX24SBF combines reliable current detection with flexible control options in a single integrated unit.
