Functional Devices RIB043P Enclosed Power Relay 480VAC 20 Amp 3PST-NO

The Functional Devices RIB043P is an enclosed power relay from the RIB (Relay In a Box) Power Series, designed for controlling building automation systems, HVAC equipment, lighting, and low-horsepower motor applications. This relay comes pre-mounted and pre-wired in a housing, saving installers the time and expense of purchasing separate components like relay, socket, mounting rail, and enclosure.

Key Features:

• One 3PST (three-pole single-throw) continuous duty normally open contact configuration rated for 20 amps
• Equipped with status LED indicator that illuminates when relay is activated
• NEMA 1 plenum-rated enclosure for versatile installation environments
• Features a protruding 1/2-inch NPT nipple from which all wires exit for simplified installation
• Includes 16-inch pre-attached leads rated for 600V
• Fast 20ms operate time for responsive switching
• Expected relay life of 10 million cycles minimum mechanical operation

Technical Specifications:

• Coil Voltage: 480 VAC, 50/60 Hz
• Contact Ratings: 20 Amp resistive @ 300 VAC or 28 VDC, 20 Amp ballast @ 277-480 VAC, 15 Amp resistive @ 600 VAC
• Operating temperature range: -30°F to 140°F
• Operating humidity: 5% to 95% non-condensing
• UL Listed (UL916 Energy Management, UL864 Fire), C-UL, CE, RoHS, California State Fire Marshal approved

This heavy-duty relay is ideal for direct switching and control of large electrical circuits including resistive loads, motors, and lighting systems. The enclosed design with plenum rating makes it suitable for installation in air handling spaces and various commercial or industrial environments.
