Product information

Description

The Pollin MKF-2PK is a professional phase monitoring relay engineered to provide comprehensive protection for three-phase electrical systems. This device continuously monitors for phase loss, phase asymmetry, and incorrect phase sequence, ensuring that connected equipment operates within safe electrical parameters. By integrating contactor contact monitoring, the relay adds an extra layer of operational safety, preventing potential damage caused by faulty switching components in industrial and commercial installations.

Advantages

This monitoring relay offers high reliability in detecting critical power supply irregularities that could otherwise lead to motor burnout or equipment failure. Its compact design allows for efficient space utilization within electrical cabinets, while the integrated contactor monitoring feature simplifies the safety circuit architecture. The device is built for durability and consistent performance, making it an essential component for maintaining the integrity of three-phase power distribution systems.

Suitable for

Industrial motor protection
Three-phase power distribution panels
HVAC system control units
Automated manufacturing machinery
Electrical infrastructure monitoring

When it may not be suitable

This device is specifically designed for three-phase systems and is not suitable for single-phase applications. It should not be used in environments where the voltage or current requirements exceed the specified 5A 250V rating, as this could lead to device failure or safety hazards.

Key specifications

Monitoring functions: Phase loss, phase asymmetry, phase sequence
Integrated contactor contact monitoring
Output rating: 1P 5A 250V
Mounting type: DIN rail TH35

How to use

The Pollin MKF-2PK is designed for installation on a standard TH35 DIN rail within an electrical enclosure. Wiring should be performed by a qualified professional in accordance with the provided wiring diagram, ensuring that all phase inputs are correctly connected to the monitoring terminals. Once installed, the device automatically begins monitoring the supply lines. The integrated contactor monitoring loop must be connected to the auxiliary contacts of the main contactor to enable the safety shutdown feature.

What to consider before purchase

Verify that your system voltage matches the device specifications
Ensure there is sufficient space on the DIN rail for installation
Confirm that your contactor has available auxiliary contacts for the monitoring loop
Check that the load current does not exceed the 5A limit

Usage recommendations

Regularly inspect the wiring connections and the status indicators on the relay to ensure the system remains protected. Periodic testing of the phase loss detection function is recommended during scheduled maintenance to verify that the safety circuit is fully operational.
