EVTSCAN DPA51CM44 3 Phase Relay Phase Protection

Description

Product Overview

The EVTSCAN DPA51CM44 3‑Phase Monitoring Relay is engineered to provide precise phase‑sequence monitoring and immediate phase‑loss detection for three‑phase industrial systems. Constructed with a robust housing and high‑grade internal components, this relay tolerates harsh electrical environments and delivers consistent performance from 208 V up to 480 V. Its compact dimensions—8.1 cm × 6.7 cm × 1.75 cm—allow easy integration into crowded control panels, while the clear indicator lights simplify troubleshooting and status verification. The device operates without a neutral connection, making it suitable for a wide range of three‑phase configurations where space and wiring simplicity are critical. Designed for durability, the relay meets IEC standards for electromagnetic compatibility and offers a long service life with minimal maintenance requirements.

Usage

Designed for demanding industrial applications, the DPA51CM44 excels in environments such as elevator drive systems, HVAC compressors, and power distribution equipment where reliable phase monitoring is essential. It safeguards motor-driven machinery by instantly shutting down or signaling an alarm when an incorrect phase sequence or a loss of phase is detected, preventing costly damage and unplanned downtime. The relay’s strong anti‑interference performance ensures accurate operation even in facilities with high electromagnetic noise, such as factories with heavy machinery, welding stations, or large variable‑frequency drives. Installation is straightforward: the relay can be mounted on DIN rails, wired directly into the control circuit, and connected to monitoring panels or PLCs for seamless integration into existing automation architectures.
