Multifunctional relay ZUBR MF2-50

ZUBR MF2-50: Your personal bodyguard for electrical appliances!
Forget about voltage drops and threats to your equipment. This is not just a relay, it is an intelligent shield that instantly responds to any deviations in the network. Customize it to your needs: control current, power, voltage - all in one compact device. Protect your home or office from fires, breakdowns and premature wear of equipment.

ZUBR MF2-50: When safety is not a compromise, but a standard!

Enhanced safety thanks to thermal protection
ZUBR MF2-50 is equipped with a built-in thermal sensor that ensures maximum safety. If the temperature inside the case exceeds 80 ° C, the device will automatically disconnect the load, and a flashing "oht" message will appear on the screen. This will prevent overheating and potential damage to the relay or connected devices. After the temperature drops to 60 ° C, the relay will automatically resume operation. For your protection, if the thermal protection is triggered more than five times per day, the relay will lock and the "oht" sign will be constantly lit. This is an indicator of a serious overheating problem that needs to be fixed. Once the cause has been eliminated and the temperature has dropped below 60 °C (the relay will indicate this by displaying a dot at the end of "oht."), simply press any button to unlock. You can always view the current temperature inside the case: during overheating, press the "i" button, and in normal mode, hold it for 21 seconds.

Simple and quick installation
Installation of the ZUBR MF2-50 is incredibly simple thanks to its standardized input-output connection. The ability to connect without using a zero terminal simplifies the process. This compact relay takes up only two standard modules (36 mm) in a DIN rail switchboard. If your room has high humidity or there is a risk of water ingress, make sure your switchboard complies with the IP55 protection class.
