## Long description

The Pollin MKF-2P is a professional phase loss and asymmetry monitoring relay engineered for the protection of three-phase electrical systems. This device continuously monitors the supply voltage to detect phase failure or voltage imbalances that could potentially damage connected equipment. With integrated contactor contact control, it provides a robust solution for industrial and commercial electrical installations, ensuring that machinery operates only under safe electrical conditions.
Advantages
The primary benefit of the Pollin MKF-2P is its ability to prevent costly equipment failure by reacting instantly to power irregularities. Its compact design allows for easy integration into existing control panels, while the built-in contactor control feature simplifies the wiring process and enhances system reliability. By maintaining strict monitoring of phase integrity, the device ensures consistent performance and extends the operational lifespan of motors and other sensitive three-phase components.
Suitable for
Industrial motor protection systems
Three-phase power distribution panels
HVAC control units
Automated manufacturing machinery
Electrical infrastructure monitoring
This device may not be suitable for single-phase electrical systems or applications where the voltage levels exceed the specified 250V rating. It is also not intended for use in environments with extreme moisture or high levels of conductive dust without appropriate protective enclosure housing.
Key specifications
Rated current: 8A
Rated voltage: 250V
Mounting type: TH35 DIN rail
Function: Phase loss and asymmetry monitoring
Control: Integrated contactor contact control
To use the Pollin MKF-2P, mount the device onto a standard TH35 DIN rail within your electrical cabinet. Connect the three-phase supply lines to the designated input terminals and wire the contactor control circuit according to the provided technical diagram. Once installed, the device will automatically begin monitoring the phases; the internal relay will trigger if a fault condition such as phase loss or significant asymmetry is detected, thereby interrupting the control circuit to protect your equipment.
What to consider before purchase
Verify that your system voltage is compatible with the 250V rating
Ensure your control circuit current requirements do not exceed 8A
Confirm availability of space on your TH35 DIN rail
Check that the device meets the specific safety requirements of your installation environment
Usage recommendations
Regularly inspect the electrical connections to ensure they remain tight and free from oxidation. Periodically test the monitoring function to confirm that the relay correctly interrupts the contactor circuit during simulated fault conditions to maintain optimal safety standards.
