H3 + P250 LSnI 4P4D N0-50-100% 250A 40kA 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 a rotary rest switch. The trigger for the overload current (Ir) and the short-term short-circuit current (Isd) can be separated. The immediate trigger for the short circuit current Ii is fixed. 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 tsd. A ready-to-use LED lights green when the trigger is ready for use and blinks orange when an internal error is detected in the trigger. Another LED starts 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. The set trigger curve can be tested and documented by means of an interface for a diagnostic and configuration tool.
