W4A MProtect is an intelligent relay designed to ensure the safety and optimal performance of motors by monitoring and controlling their activation. It features an integrated current protection system that helps prevent motor damage. In addition, it can be triggered by external level sensors and time-based controllers, offering flexibility for various applications. The device maintains a comprehensive log of all events and actions, providing a detailed history of activations and operating conditions for future analysis.
Whether operating in domestic or industrial environments, W4A MProtect is the safe solution to operate your motor.
What sets us apart
Current-based fault control
Through real-time analysis of current on all three phases, it enables the detection of water shortages, leaks, mechanical failures and electrical faults.
Intelligent history analysis
With intelligent history analysis and real-time profiling, you can avoid maintenance and energy costs through early detection of faults and leaks.
Extended and secure connectivity
With Wi-Fi and Bluetooth connectivity, it offers flexible options adapted to your needs, using secure communications that integrate next-generation security standards.
Actuation timer
The system integrates controllers that allow weekly and/or cyclic scheduling.
Remote control via Internet
Through a subscription, you can manage and monitor your devices from anywhere.
History logging and consultation
Continuous logging of consumption, actuations and changes in state and operation of level sensors. Error reporting and notifications.
