Description

Product Overview

Based on ATST Electric’s core concept of “Precise Control, Safe and Reliable”, MK-05 Phase Failure Device provides an effective protection solution for three-phase electrical equipment.​
The device continuously monitors the three-phase power supply status and detects phase loss conditions that may affect equipment operation. When a phase failure occurs, MK-05 provides a protection signal to control the connected equipment, helping prevent motor overheating, abnormal operation and potential damage caused by unstable power conditions.​
Three-phase motors and industrial equipment require stable power supply to maintain normal operation. MK-05 helps improve system reliability by providing automatic phase failure protection without requiring complex control systems.​
With compact design, convenient installation and reliable protection performance, MK-05 can be integrated into motor control panels, distribution cabinets and industrial automation systems for various three-phase applications.​
