H3 + P630 Energy 3P3D 630A 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 a rotary rest switch. 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 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. Another LED signals the overtemperature in the release unit. This is red when it is exceeded 105 ° C internally. 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. This is shown by an additional LED. It lights up orange when the contact is closed. The set trigger curve can be tested and documented by means of an interface for a diagnostic and configuration tool.
