Functional Devices RIB04P Power Relay 20A DPDT 480V NEMA 1 Enclosed

Description

Product Overview

The Functional Devices RIB04P Power Relay is engineered for high‑performance industrial applications where reliability and precision are paramount. This DPDT (double pole, double throw) relay handles up to 20 Amps at 480 Vac, delivering robust switching power while maintaining a compact footprint within a NEMA 1 enclosure. Constructed from UL‑listed, CUL‑approved, and CE‑certified materials, the relay features a durable metal housing that resists corrosion and mechanical stress. An integrated LED indicator provides instant visual feedback on coil energization, and the 16‑inch pre‑wired leads simplify wiring in tight panels. The coil operates at 480 Vac, matching common industrial power supplies, and the relay’s contact design ensures low resistance and fast response times, typically around 18 milliseconds.

Usage

Designed for a wide range of industrial control scenarios, the RIB04P excels in motor control circuits, HVAC systems, conveyor belt drives, and automated manufacturing equipment. Its DPDT configuration allows for versatile wiring schemes, enabling both on‑off and polarity‑reversal functions without the need for additional components. The relay’s NEMA 1 enclosure makes it suitable for indoor installations where dust, moisture, and accidental contact are concerns. Engineers and technicians appreciate the 16‑inch leads, which reduce the need for extra terminal blocks and accelerate assembly time. Whether used in a PLC‑controlled process line or a standalone control panel, the RIB04P delivers consistent performance under continuous duty cycles.
