IDEC Relays RR3B-UAC24V Relay

Professional-grade IDEC RR3B-UAC24V relays are industry-standard components for heavy-duty HVACR and industrial control panels. This 3PDT power relay features a 24VAC coil voltage and is engineered for high-capacity switching with a 10A contact rating. Built with silver contacts, these RR Series midget power relays provide superior electrical conductivity and a mechanical life exceeding 10 million cycles. The 11-blade terminal configuration ensures a secure, high-integrity connection to matching IDEC relay sockets, making them the preferred choice for contractors requiring reliable multi-pole switching in high-cycle applications. Designed to handle inductive loads including 1/4 HP at 120VAC and 1/3 HP at 240VAC, this relay is a drop-in replacement for standard 24 volt AC control systems. Whether you are managing industrial machinery or complex HVAC building automation, the IDEC RR3B-UAC24V delivers the durability needed to minimize downtime and maintain consistent system performance.

Key Benefits:

• High Switching Capacity: Reliable 10 Amp 3PDT (3 Form C) contacts allow for simplified control of multiple circuits.
• Robust Construction: Features high-purity silver contact material to maintain low contact resistance over a long service life.
• Standard Blade Terminals: 11-blade "Quick Connect" style terminals provide a stable fit into standard DIN-rail or surface-mount sockets.
• Wide Operating Range: Performs efficiently in temperatures ranging from -13°F to +158°F (-25°C to +70°C).
• Industrial Regulatory Compliance: Meets UL, CSA, and CE standards for safety and performance in professional installations.

Common Questions:

• What is the difference between a pin and blade terminal RR relay? Blade terminals (like this RR3B-UAC24V) use flat-style connectors for square-base sockets, whereas pin terminals use octal or 11-pin tubular bases. Always verify your socket type before installation.
• Can this relay handle motor loads? Yes, it is rated for 1/4 HP at 120VAC and 1/3 HP at 240VAC, making it suitable for small fan motors and actuators.
• What is the typical response time? The relay features a fast maximum operating and release time of approximately 25ms, making it ideal for timing-sensitive control logic.
