Functional Devices RIB013P Relay

The Functional Devices RIB013P is a robust 120V 20A 3PST-N/O Power Control Relay designed for heavy-duty switching in demanding HVACR and industrial automation environments. This enclosed power relay features a triple pole single throw configuration, allowing for the simultaneous control of three separate circuits or high-amperage multi-phase loads from a single 120VAC coil input. Housed in a NEMA 1 rated enclosure, the RIB013P is engineered for durability and ease of installation, featuring a 1/2" NPT nipple for direct mounting to electrical boxes. Experienced contractors utilize this heavy-duty relay for motor control, lighting contactors, and heat pump sequencing where reliable inductive load switching is critical. The gold flash contacts ensure signal integrity, while the external LED indicator provides immediate visual confirmation of the relay coil status during troubleshooting. Built to handle 20-amp resistive loads, this unit serves as a reliable interface between low-power controllers and high-voltage equipment.

Key Benefits for Technical Applications:

• High Amperage Capacity: Rated for up to 20A resistive and 1HP at 120V, suitable for direct motor control.
• Pre-Wired Design: Features 12-inch color-coded leads to streamline field wiring and reduce installation labor.
• Status Monitoring: Integrated LED indicator allows technicians to verify coil energization without a dedicated multimeter probe.
• 3PST Configuration: Enables switching of three independent poles, making it ideal for 3-phase equipment or multiple branch circuits.
• NEMA 1 Enclosure: Provides protection for internal components while maintaining a compact footprint for tight mechanical spaces.

Common Technical Questions:

Can the RIB013P be used for 3-phase motor switching?
Yes, the 3PST-NO relay configuration is specifically designed to handle three poles simultaneously, making it an efficient solution for 3-phase power control within its voltage and amperage ratings.

What is the primary difference between the RIB013P and standard RIB series relays?
The RIB013P is a power relay tailored for high-current applications, offering three normally open poles rather than the single-pole double-throw (SPDT) configuration found in smaller pilot duty models.

Is this relay suitable for outdoor mounting?
The RIB013P is rated for NEMA 1 indoor use. For outdoor applications or environments exposed to moisture, it must be installed inside a secondary NEMA 3R or NEMA 4X rated weather-tight enclosure.
