Functional Devices ribm023pn Panel Relay 30A 3PDT 208-277V

Product Description

The FUNCTIONAL DEVICES ribm023pn is a 4-inch track-mount panel relay rated for 30 amps with a 3PDT contact configuration and a 208-277 Vac coil. Designed for DIN-rail or track installation inside electrical panels and control enclosures, this relay switches three independent poles simultaneously, making it well suited for multi-phase load control and lighting contactors. The coil operates across the 208-277 Vac range, covering most common commercial line voltages. It carries a UL Listed approval and is rated for a minimum mechanical life of 10 million cycles, supporting long-term reliability in demanding building-automation and HVAC control applications. Licensed electricians and controls technicians are the primary installers.

This relay fits into commercial and light industrial control panels where 3PDT switching is required at line voltage. Typical applications include HVAC equipment control circuits, lighting relay panels, and building automation system output modules. The 208-277 Vac coil voltage makes it compatible with the standard single-phase and three-phase distribution voltages found in commercial buildings. The green color coding aids visual identification inside densely populated enclosures.

Key Features

• 30 amp rated contacts handle substantial resistive and inductive load switching
• 3PDT contact arrangement provides three simultaneously switched poles in a single relay body
• 208-277 Vac coil covers standard commercial line voltages without a separate transformer
• Track or DIN-rail mount design simplifies installation inside existing panels
• Rated for 10 million cycles minimum mechanical life for long service intervals
• UL Listed and rated for -30 to 140 degrees F operating temperature range

Compatibility

Designed as an OEM-style track-mount panel relay for commercial HVAC control panels, lighting panels, and building automation enclosures requiring 3PDT switching at 208-277 Vac coil voltage.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the panel before mounting or wiring the relay. Verify that the control circuit coil voltage matches the supply before energizing. Confirm that the connected load does not exceed the 30 amp contact rating for the conductor and overcurrent protection used.
