Functional Devices RIB043P Relay

The Functional Devices RIB043P is a heavy-duty 480V 20A 3PST-NO enclosed relay designed for high-voltage industrial and commercial HVACR applications. Engineered for switching 3-phase motor loads and lighting circuits, this pilot-controlled relay features NEMA 1 enclosure protection, ensuring durability in mechanical rooms. This unit utilizes a triple pole single throw normally open configuration, making it ideal for 480 VAC power switching without requiring additional external housing. The RIB043P relay simplifies the interface between low-voltage control systems and high-voltage equipment. With a 20 Amp resistive rating, it provides reliable performance for electric heat sequencing and fan motor control. Its compact design allows for quick installation on standard 1/2-inch conduit knockouts, reducing labor time for field technicians troubleshooting high voltage relay maintenance.

Key Benefits for Technicians:

• Industrial Load Management: Rated for up to 480 VAC, suitable for large horsepower motors and heavy industrial equipment.
• Pre-Wired Convenience: Includes distinct color-coded leads to ensure rapid wiring and minimize installation errors.
• Integral Enclosure: The NEMA 1 housing eliminates the need for separate junction boxes, saving space and material costs.
• Internal LED Indicator: Provides immediate visual confirmation of the relay coil status for efficient troubleshooting.
• Versatile Mounting: Includes a 1/2-inch NPT nipple for direct mounting to electrical cabinets and junction boxes.
