## Long description

The ZAMEL CKM-13 is a professional digital monitoring relay engineered to provide precise oversight of three-phase electrical systems. By continuously monitoring phase sequence and detecting phase loss, this device acts as a critical safety component for electrical installations. It features an integrated voltage indicator that allows for real-time observation of power supply status, ensuring that connected equipment operates within safe parameters and preventing potential damage caused by power irregularities.
Advantages
This relay offers high reliability in protecting sensitive electrical machinery and infrastructure from the risks associated with incorrect phase rotation or power supply failure. Its digital architecture ensures accurate detection and rapid response times, which are essential for maintaining system stability. The inclusion of a built-in voltage indicator simplifies the diagnostic process, allowing technicians to quickly verify the state of the power supply without the need for additional measuring instruments. The compact design facilitates easy installation in standard electrical cabinets, making it a versatile solution for various power management needs.
Suitable for
Industrial automation systems
Residential three-phase power installations
Protection of electric motors and pumps
HVAC control panels
Building management systems
This device may not be suitable for single-phase electrical systems or applications where the voltage levels fall outside the specified operating range of the relay. It is also not intended for use in environments with extreme moisture or high levels of conductive dust unless housed in an appropriate protective enclosure.
Key specifications
Monitoring functions: Phase sequence and phase loss
Display: Integrated voltage indicator
System compatibility: Three-phase electrical networks
Mounting type: DIN rail
Application: Industrial and residential electrical protection
To use the ZAMEL CKM-13, the device must be mounted on a standard DIN rail within an electrical distribution board. Connect the three-phase power supply lines to the designated input terminals according to the wiring diagram provided with the unit. Once powered, the relay will automatically begin monitoring the phase sequence and voltage levels. The integrated indicator will display the status, allowing for immediate visual confirmation of the power supply condition.
What to consider before purchase
Verify that your electrical system is a three-phase configuration
Ensure the installation space meets the requirements for DIN rail mounting
Check that the operating voltage matches your specific network parameters
Confirm that the device meets the safety standards required for your specific application
For optimal performance and safety, ensure that all electrical connections are tightened securely and that the device is installed by a qualified electrician in accordance with local electrical codes. Regularly inspect the indicator to ensure the system remains within normal operating parameters.
