IDEC Relays RR3B-ULAC24V Relay

The IDEC RR3B-ULAC24V is a heavy-duty 3PDT relay engineered for reliable switching in demanding HVACR and industrial control environments. This 24VAC power relay features a robust 10A contact rating, making it an ideal choice for managing multi-circuit loads, interlocks, and motor control signals. Designed with 11-blade terminals, this unit integrates seamlessly into standard relay sockets, ensuring efficient field replacement and secure electrical connectivity. The inclusion of a built-in LED indicator provides immediate visual confirmation of coil energization, which is critical for rapid system diagnostics and reducing downtime during service calls.

As a core component within the IDEC RR Series, the RR3B-ULAC24V utilizes silver (Ag) contacts to maintain low contact resistance and long-term conductivity even under high-cycle conditions. This electromechanical relay is optimized for 50/60Hz applications and meets stringent UL and CSA safety standards, providing the durability required for control panels and automation equipment. Whether used for sequencing air conditioning components or as an isolation relay in complex machinery, this 3-pole double-throw configuration provides the versatility needed for professional-grade installations.

• Versatile 3PDT Configuration: Manages up to three independent circuits simultaneously with a 10-Amp resistive capacity.
• Visual Diagnostics: Features an integrated LED indicator for real-time troubleshooting of the control signal.
• Industry Standard Mounting: Equipped with blade terminals for quick, plug-in installation in DIN rail or panel-mount sockets.
• High-Frequency Reliability: Engineered for 24V AC control circuits with stable performance across 50/60Hz frequencies.

• What socket is compatible with this relay? The RR3B-ULAC24V typically pairs with 11-blade sockets like the SR3B-05 for DIN rail or surface mounting.
• Can this relay handle inductive motor loads? Yes, its 10A rating is suitable for general-purpose power switching, though always verify the specific FLA/LRA requirements of your motor against the 3PDT contact specs.
• Is the indicator light standard? Yes, the "L" in the part number indicates a built-in LED indicator for easy power status monitoring.
