Entes Phase Failure Relay-Voltage Monitoring, Protection & Control

Entes Phase Failure Relay is a critical safety and monitoring device designed to protect 3-phase electrical equipment, such as motors, pumps, and compressors, from damage caused by power supply issues. By continuously monitoring the voltage of all three phases, this relay instantly identifies faults and de-energizes the circuit, preventing costly equipment failures and ensuring operational continuity. Its compact, DIN-rail mountable design makes it an ideal solution for a variety of industrial and commercial control panels.

Features
Multi-functional Protection: The relay offers comprehensive protection by monitoring for several key parameters:
Phase Failure (Loss): Immediately detects the absence of one or more phases and trips the circuit.
Phase Sequence Error: Prevents motors from running in the wrong direction by detecting incorrect phase rotation.
Voltage Unbalance (Asymmetry): Monitors for a significant voltage difference between phases, which can cause motor overheating and damage. Some models have adjustable asymmetry settings.
Adjustable Time Delays: Many models feature adjustable “ON” and “OFF” delay times. This prevents nuisance tripping from minor, temporary voltage fluctuations, allowing the system to ride through brief disturbances without unnecessary shutdowns.
Compact Design: The slim, modular housing is designed for efficient use of space within control panels, making installation straightforward on a standard DIN rail.
LED Status Indicators: The front panel includes clear LED indicators that provide a quick and easy visual diagnosis of the power supply status and the type of fault detected (e.g., phase failure, phase sequence error).
High-Quality Construction: Built with a durable, non-flammable plastic case and high-quality internal components, the relay is designed for reliable long-term performance in demanding industrial environments.

MKC-01 is best for basic protection needs.
✅ MKC-05 is ideal when you need adjustable delay and enhanced flexibility.
