Product Overview
Based on ATST Electric’s core concept of “Precise Control, Safe and Reliable”, MKC-05/MKC-06 Phase Failure Devices are developed to provide reliable protection for three-phase electrical equipment.
The devices continuously monitor the condition of the three-phase power supply and detect abnormal situations such as phase loss. When a phase failure occurs, the protection device provides a control signal to disconnect or stop the connected equipment, helping prevent motor overheating, abnormal operation and potential equipment damage.
MKC-05/MKC-06 are designed for applications where stable three-phase power is essential. With compact structure and convenient installation, they can be easily integrated into electrical cabinets, motor control panels and automation systems, providing an effective protection solution for industrial equipment.
Main Features
1. Phase failure detection: Monitors three-phase power status and quickly identifies missing phase conditions.
2. Reliable equipment protection: Helps prevent motor damage, overheating and abnormal operation caused by phase loss.
3. Continuous power monitoring: Provides real-time supervision of three-phase electrical conditions during equipment operation.
4. Fast protection response: Sends a control signal when a phase fault occurs to improve system safety.
5. Compact modular design: Space-saving structure allows easy installation in control panels and electrical cabinets.
6. Simple wiring and maintenance: Clear terminal design makes installation and troubleshooting more convenient.
7. Stable long-term operation: Designed for continuous use in industrial and commercial electrical environments.
8. Wide application compatibility: Suitable for motors, pumps, compressors and various three-phase electrical equipment.
