Description

Product Overview

The QANYEGN DPA51CM44 3‑phase monitoring relay is engineered to provide precise phase‑sequence monitoring, voltage detection, and current overload protection for a wide range of industrial applications. Built to meet IP20 standards, this relay offers robust protection against dust and accidental contact while maintaining a compact footprint that fits easily onto standard DIN‑rail panels. With a current rating of 5 A and a voltage operating range of 208‑480 VAC, the device is suitable for medium‑size motor drives, elevator control panels, HVAC units, and other critical power systems. The relay features screw‑terminal connections for straightforward wiring, a white housing with silver contacts for clear visual identification, and an automatic operation mode that eliminates the need for manual configuration. Its durable construction, combined with a lightweight design of just 2.47 ounces, ensures reliable performance even in demanding environments.

Technical specifications include a 5 A current rating, DIN‑rail mounting type, and compliance with industry standards for safety and electromagnetic compatibility. The relay’s dimensions—3.54 × 2.76 × 0.79 inches—allow it to be installed in tight spaces without sacrificing functionality. The product is manufactured by QANYEGN, a brand known for delivering high‑quality electrical components that meet rigorous performance criteria. The part number QANYEGNsvg80aury2 uniquely identifies this model, ensuring easy sourcing and replacement when needed.

Usage

Designed for versatility, the DPA51CM44 relay excels in environments where accurate phase monitoring is essential for equipment safety and efficiency. In motor applications, the relay continuously checks the correct phase sequence, preventing damage caused by phase loss or reversal. For elevator systems, it safeguards the drive circuitry by detecting abnormal voltage conditions and initiating protective shutdowns, thereby extending the lifespan of costly components. HVAC installations benefit from the relay’s ability to monitor multiple phases, ensuring balanced power distribution and reducing the risk of overheating in compressors and fans.

Installation is straightforward thanks to the DIN‑rail mounting system and screw‑terminal connections. Technicians can quickly secure the relay onto existing panels, reducing downtime and labor costs. The automatic operation mode means the relay self‑configures based on the detected power conditions, making it an ideal choice for both new installations and retrofits. Its compact size allows it to be integrated into confined control cabinets, while the white exterior provides a neutral aesthetic that blends with most industrial panel designs.

Beyond traditional industrial settings, the relay is also suitable for renewable energy systems such as solar inverters and wind turbine controllers, where phase monitoring helps maintain grid compliance and protect sensitive power electronics. Its wide voltage range accommodates the varying output levels typical of renewable sources, and the 5 A rating ensures sufficient capacity for most monitoring tasks without the need for additional current‑handling devices.
