Functional Devices RIB02P Relay

The Functional Devices RIB02P is a heavy-duty Enclosed Power Relay engineered for demanding commercial HVAC and building automation applications. Operating with a 208-277VAC coil voltage, this double pole double throw (DPDT) relay provides reliable switching for dual-circuit control logic. As part of the "Relay in a Box" series, it comes pre-wired in a NEMA 1 housing with a 1/2-inch NPT nipple, significantly reducing field installation time by eliminating the need for separate sockets or external enclosures. With a 20 Amp contact rating, the RIB02P is built for HVAC motor control, inductive loads, and large resistive heaters. The integrated LED status indicator allows for immediate visual verification of relay activation during troubleshooting. While versatile, note that the contacts are not rated for electronic ballasts. This plenum-rated relay features a 10-million-cycle mechanical life, ensuring long-term stability in high-cycle industrial energy management environments.

• Reduced Installation Labor: Pre-wired 16-inch leads and internal housing eliminate the assembly of individual components on-site.
• High Load Capacity: Rated for 20A resistive and up to 3 HP at 480VAC, making it suitable for heavy-duty power control relay applications.
• Visual Diagnostics: The built-in LED provides a clear "activated" signal to streamline service calls.
• Versatile Mounting: Includes a 0.50-inch NPT nipple for secure attachment to junction boxes or control panels.
• Gold Flash Contacts: Provides superior electrical connectivity and resists surface oxidation in standard operating environments.

What is the difference between a DPDT and SPDT relay in this series?
A DPDT relay like the RIB02P controls two separate poles, allowing you to switch two distinct circuits simultaneously with a single coil trigger, whereas an SPDT only manages one circuit.

Can I use the RIB02P to control LED drivers?
No. While this unit handles magnetic ballasts up to 20A, it is not rated for the high inrush currents typical of electronic ballasts or LED lighting control. Using it for these loads may cause premature contact welding.

Will this relay pull in with a 120V control signal?
No. The RIB02P requires a minimum pull-in voltage of 160VAC and is specifically designed for 208-277VAC coil sensing. For 120V applications, use a compatible RIBU1C or RIB01P model.
