Automatic phase switch EPF-44 002470281

Automatic phase switch – reliable power supply in your circuit

This EPF-44 automatic phase switch from ETI Polam is a key element ensuring continuity of power supply in electrical installations. The device is designed to automatically switch between phases in the event of a voltage failure in one of the phases, which guarantees uninterrupted operation of connected devices. This is particularly important for receivers requiring a stable power supply, such as gas boilers, central heating pumps or refrigerators.

Construction and application

The EPF-44 switch is designed for mounting on a TH35 rail. Compact dimensions (54 mm width, 90 mm height and 65 mm depth) allow for easy integration with existing electrical infrastructure. Screw terminals facilitate and speed up the connection of wires, saving time during installation. The device is ideal for both professional installers and end-users looking for a reliable solution to protect their devices.

The EPF-44 finds application in:

• Fire alarm power supplies

• Powering single-phase receivers requiring continuous power supply (e.g. gas boilers, central heating pumps, refrigerators)

• Cooperation with contactors to increase the permissible load

• Automatic backup power switching systems

Key features and benefits

• Fast response: The maximum permissible time delay in the event of a power failure is only 0.2 seconds, which minimizes downtime in the operation of connected devices.

• Precise operating voltage: The setting value of the operating voltage in the range of 180…210 V ensures optimal operation in various network conditions.

• Three normally open (NO) contacts: The presence of three normally open (NO) contacts increases the flexibility and possibilities of using the switch in various installation configurations.

• Easy installation: Screw terminals allow quick and secure connection of wires without the need for specialized tools.

• Compact dimensions: Allow mounting in a limited space without compromising functionality.

• Solid construction: Ensures long-lasting and reliable operation of the device even in difficult operating conditions.

Thanks to these features, the EPF-44 is an investment in the safety and comfort of using your electrical installation.
