The Functional Devices RIB243P is a three-pole single-throw (3PST) relay designed for switching applications in HVAC, building automation, and industrial control systems. This heavy-duty relay handles up to 20 amps per pole and operates on 24 VAC/DC control voltage, making it ideal for controlling motors, compressors, heating elements, and other high-current loads.

Key Features:

• 3PST configuration with normally open (N/O) contacts
• 24 VAC/DC coil voltage for broad compatibility
• 20 amp resistive rating per pole for heavy-duty applications
• Enclosed relay-in-a-box (RIB) design for easy DIN rail or surface mounting
• LED coil status indicator for quick troubleshooting
• UL 508 listed for safety compliance

The RIB series from Functional Devices provides reliable switching performance with built-in protection and easy installation. The compact enclosed design eliminates the need for separate relay sockets and housings, reducing installation time and panel space requirements. Ideal for commercial and industrial environments where switching multiple circuits simultaneously is required.
