All-in-one protection for the electrical system ZUBR MF2-40 (40A) protects devices from high and low voltage and dangerous neutral wire breakage. In addition, the device acts as an effective current control relay , limiting current or power consumption and preventing system overload. In case of voltage deviations, the voltage relay immediately switches off the load, while when the current or power is exceeded, an automatic shutdown is triggered with a delay set by you.

Main advantages and technical features:

  • Three informative displays: The compact housing (only 2 DIN modules wide) is equipped with three digital displays that simultaneously show voltage, current and power in real time. In standby mode, the display brightness is conveniently adjustable.

  • TrueRMS measurement accuracy: Thanks to the TrueRMS algorithm, the current relay and voltage relay measurement results are extremely accurate. This means that the device switches off the load just before poor quality current can damage your equipment.

  • Professional Pro Mode: Ideal for unstable power supply. Pro mode prevents unnecessary shutdowns when voltage fluctuations are short-lived and safe for connected devices.

  • Adjustable switch-on delay: The delay can be flexibly set from 3 to 999 seconds. This is especially important for compressor-powered appliances (refrigerators, air conditioners, heat pumps), where overload protection and a longer switch-on delay (recommended 2-3 minutes) significantly extend the life of the equipment.

  • Emergency event memory: The device stores the last 100 alarm conditions (for example, voltage reading at the moment of shutdown) in a non-volatile memory, which helps to analyze network problems quickly and conveniently.
