Functional Devices RIB24P30 Relay

The Functional Devices RIB24P30 is a heavy-duty 30A DPDT power control relay engineered for high-amperage HVAC and industrial switching applications. This enclosed relay simplifies field installations by integrating the relay, LED status indicator, and specialized transient protection into a single NEMA 1 housing, eliminating the need for separate DIN rails or external sockets. Designed with a 24VAC/DC continuous duty coil, it provides reliable low-voltage control for high-amperage motor loads, compressors, and lighting circuits. The unit features gold flash contacts and is UL listed for use in plenum spaces, making it a versatile choice for energy management systems. With 16-inch 600V rated color-coded wire leads and a 0.75-inch NPT nipple, the RIB24P30 ensures a secure, code-compliant connection to standard electrical knockouts. For technicians managing inductive loads, this double pole double throw relay delivers a mechanical life of 10 million cycles, providing long-term HVAC relay performance in demanding environments.

Key Benefits

• High Contact Rating: Robust 30 Amp resistive capacity at 300VAC, suitable for direct switching of large HVAC fans and motors.
• All-in-One Enclosure: Pre-wired NEMA 1 housing reduces installation time and labor costs on the job site.
• System Monitoring: Integrated LED indicator provides immediate visual confirmation of the relay coil status.
• Plenum Rated: UL916 and UL864 approvals certify the unit for safe installation within environmental air spaces.
• Dual-Pole Flexibility: The DPDT configuration allows for simultaneous control of two separate circuits or high-voltage polarity switching.

Common Questions

Can the RIB24P30 handle 277V lighting loads?
Yes, the RIB24P30 is rated for 20 Amp ballast at 277–480 VAC, making it compatible with high-voltage industrial lighting systems, though it is not rated for electronic ballasts.

What is the purpose of the gold flash on the contacts?
The gold flash prevents contact oxidation during storage and provides reliable low-signal switching, though the primary rating is for high-power 30A applications.

How do I mount this relay to a control panel?
The unit is typically nipple-mounted through a standard 0.75-inch NPT knockout on the equipment or junction box and secured with the included locknut.
