Hager HMS160NC h3+ P160 3P3D 160A 50kA circuit breaker

Circuit breaker h3+ P160 Energy 3P3D 160A 50kA CTC. The molded case circuit breaker in accordance with DIN EN 60947-2 protects the electrical system and networks against overload and short circuit. The tripping curve of the electronic trip can be set via the integrated OLED display, via a connectable door-mounted display or by a terminal with an Internet browser and WiFi using the configuration tool. The tripping curves for the overload current (Ir), the short-term delayed short-circuit current (Isd) and the undelayed short-circuit protection (Ii) as well as the time delay tr in the event of overload and the time delay tsd for short-term delayed short-circuit tripping can be set separately. In addition, the tripping curve can be adjusted inversely proportionally using an activatable I²t function between the short-circuit currents Ii and Isd and the short-term delayed and undelayed tripping time. The ready LED lights up green when the trigger is ready for use and flashes orange when an internal error is detected in the trigger. The LED for the overcurrent indication starts to flash red when I = 105% Ir and lights up red continuously when I > 112% Ir. The three different operating states can be identified by the position of the toggle (ON = top, OFF = bottom, triggered = middle position). A device for locking the switching state in the ON or OFF position is integrated and can be used with a standard padlock without additional accessories. The trigger mechanism can be tested and the main contacts opened using a trigger button. A hinged cover with a captive quick-release screw allows access to the installation space for optional auxiliary contacts and other triggers. Integrated accessories can be recognized and identified via the viewing window without opening the hinged cover. A potential-free alarm contact for the switch-off warning in the event of a risk of shutdown due to overload is integrated as standard. This is closed when I > 90% Ir (default value, changeable). This is indicated by an additional LED. It lights up orange when the contact is closed. An additional potential-free contact can be used in the trip unit for up to 12 individual alarms. The set trip curve can be tested and documented using an interface for a diagnostic and configuration tool. The integrated measuring technology measures all energies with an accuracy of class 1 according to IEC 61557-12. The partial energy storage can be reset. The h3+ Energy molded case circuit breaker can also be used to calculate power consumption values. These calculations can be made using a fixed or sliding interval that can be set from 5 to 60 minutes in steps of 1 minute. The calculation window can be synchronized with a signal sent by the communication system via the COM module. These consumption values can be used to create trends and forecasts based on this data. They provide basic data for developing a load profile. In addition, the h3+ Energy molded case circuit breakers measure the total harmonic distortion (THD) of the current and voltage.
