H3 + P250 Energy 4P4D N0-50-100% 40A 70kA FTC.The compact power switch in accordance with DIN EN 60947-2 protects the electrical system and networks from overload and short circuit. The trigger curve of the electronic trigger can be set by means of the integrated OLEDdisplay, a connection to the door installation display or by means of an end device with Internet browser and Wlan via the configuration tool. Separated are the trigger for the overload current (Ir), the short-term short-circuit current (Id) and the immediate short-circuit protection (Ii), as well as the time delay for overload and the time delay tsd for short-term short-circuit trigger. In addition, an activated I ² t function can be used to adjust the trigger curve proportionally between the short-circuit flow Ii and Isd and the short-term delayed and undelayed release time. The neutralconductor protection can be adjusted with a controller to the position OFF, 50% of Ir and Isd or 100% of Ir and Isd. The time delay remains as with tr and ts.The stand-up LED lights green when the trigger is ready for use and blinks orange when an internal error is detected in the trigger. The LED for the overcurrent display begins to flash red when I = 105% Ir, and lights permanently red when I 112% Ir. At the position of the slave the three different operating states are visible (one = above, OFF = below, triggered = middle position). A device for locking the switching state in ON or off position is integrated and can be used with a commercial padlock without additional accessories. A trigger key can be used to test the trigger emanism and open the main contacts. A folding cap with an unlegible quick screw allows access to the installation room for optional help contacts and other triggers. Integrated accessories can be identified and identified via the view window without opening the folding cover. A potential-free alarm contact for the switch-off warning at the risk of overload shutdown is integrated by default. This is closed at I 90% Ir (default value, variable). This is shown by an additional LED. It lights up orange when the contact is closed. In the release unit, an additional potential-free contact can be used for up to 12 individual alarms. The set trigger curve can be tested and documented by means of an interface for a diagnostic and configuration tool. The integrated measurement technology measures all energies with an accuracy of class 1 according to IEC 61557-12. The partial energy storage can be reset. The compact power switch h3 + Energy can also be used to calculate power consumption values. These calculations can be made using a fixed or sliding interval, which can be set from 5 to 60 minutes in steps of 1 minutes. The calculation window can be synchronized with a signal sent by the communication system via the COMmodule. These consumption values can be used to produce trends and forecasts based on these data. They provide basic data for the development of a load profile. In addition, the compact power switches h3 + Energy measure the entire harmonious distortion (THD) of the current and the voltage.
