Universal automatic electronic phase switch PEF-301 NTPEF3010

Stable power supply and protection for your installation

The universal automatic phase switch PEF-301 is an intelligent solution for powering single-phase loads in three-phase networks. The device ensures uninterrupted power delivery, especially for sensitive equipment, protecting it from voltage fluctuations. It is ideal for both home workshops and demanding industrial conditions.

PEF-301 monitors the voltage on each phase and automatically selects the one that offers the best power supply parameters. Even if there are problems with one of the phases, your devices will continue to operate without interruption. This is crucial for maintaining continuity of operation and avoiding costly downtime.

Versatility and flexibility of application

The PEF-301 switch is designed to work with loads up to 3.6 kW (16A). In such cases, it powers them directly. For higher powers – exceeding 3.6 kW – the device controls external contactors (which are not included in the set), enabling protection and stabilization of the power supply for more demanding loads. This makes the PEF-301 extremely versatile and adapts to the needs of different installations.

Additionally, the switch offers protection against overvoltage or undervoltage and phase loss, which increases safety and protects connected devices from damage.

User comfort and reliability

The PEF-301 switch is easy and intuitive to install – the device is mounted on a DIN rail in a standard housing with a width of 4 DIN (72 mm). LED indicators inform about the operating status of the device, and the ability to adjust parameters allows for precise adaptation to the specifics of the installation. Solid construction and the use of high-quality components guarantee long-lasting and trouble-free operation for years. The manufacturer – Novatek-Electro – offers a 5-year warranty, which confirms the high quality of the product.
