C400/10/1/1/1/00

The C400/10/1/1/1/00 is an electronic monitoring and protection unit specifically designed for three-phase AC motors. It integrates multiple protection functions to monitor critical parameters such as motor current, phase sequence, and imbalance in real time. This compact and easy-to-install device is designed to replace traditional motor protection solutions, such as thermal relays, providing more precise and comprehensive protection to effectively extend the motor’s service life and enhance system reliability.

Main Features

Overload Protection: Precisely monitors motor current to prevent motor damage caused by prolonged overload and overheating.

Stall Protection: Rapidly cuts off power supply when the motor stalls or takes too long to start, preventing coil burnout.

Phase Loss Protection: Immediately activates protection when any phase power is lost, preventing motor damage from continued operation under phase loss conditions.

Phase Sequence Protection: Monitors power phase sequence to prevent motor reversal, particularly critical in equipment requiring unidirectional operation.

Current imbalance protection: Monitors the balance of three-phase currents. When the imbalance exceeds the set value, an alarm is triggered, typically indicating issues with the motor windings, power supply, or wiring.

Fault diagnosis: Provides detailed fault status information via LED indicator lights or communication interfaces, facilitating rapid problem identification.
