## Summary description

The Pollin AZF-3 is an automatic phase switch designed for 16A 250V electrical systems. It ensures continuous power supply by automatically selecting the optimal phase in three-phase installations. Designed for standard TH35 DIN rail mounting, this device is essential for protecting sensitive equipment from phase loss or voltage drops, providing reliable power management in residential and industrial electrical distribution panels.

## Long description

The Pollin AZF-3 is an automatic phase switch engineered to maintain a continuous power supply in three-phase electrical systems. By monitoring the input voltage across three phases, the device automatically selects the most stable phase to power connected single-phase loads. This ensures that equipment remains operational even if one or two phases experience a voltage drop or total loss, making it a critical component for reliable electrical distribution.
Advantages
This automatic phase switch provides seamless transition between phases, minimizing downtime for sensitive electronic devices. Its compact design allows for efficient space utilization within electrical distribution panels, while the robust construction ensures long-term operational stability. By prioritizing the healthiest phase, it effectively protects connected appliances from the risks associated with phase failure and voltage instability.
Suitable for
Residential electrical panels requiring phase redundancy
Industrial control systems for single-phase equipment
Server rooms and telecommunications infrastructure
Emergency lighting and security systems
This device is not suitable for three-phase motors or equipment that requires all three phases to operate simultaneously. It is designed exclusively for single-phase loads and cannot be used to balance loads across all three phases in a three-phase circuit.
Key specifications
Rated current: 16A
Rated voltage: 250V
Mounting type: TH35 DIN rail
System compatibility: Three-phase input, single-phase output
How to use
The device is designed for installation on a standard TH35 DIN rail within an electrical distribution board. Wiring should be performed by a qualified electrician, ensuring that the three-phase input lines are connected to the designated terminals and the single-phase load is connected to the output terminal. Once installed, the device operates autonomously, continuously monitoring the input phases and switching to the optimal one without requiring manual intervention.
What to consider before purchase
Verify that the total load current does not exceed 16A
Ensure the installation environment is free from excessive moisture and dust
Confirm that the device is compatible with your existing three-phase distribution system
Usage recommendations: Regularly inspect the electrical connections for tightness and ensure the device is kept in a clean, dry environment to maintain optimal performance and safety.
