Hager HEJ400GR Circuit breaker 1 pc(s) Adjustment range (amperage): 400 A (max)

Power switch h3 X630 LSNi 3P3D 400A 70kA FTC. This compact circuit breaker complies with DIN EN 60947-2 and protects the electrical system and networks against overload and short circuit. The trigger curve of the electronic release can be set via rotary locking switch. The triggers for the overload current (IR) and the short-time delayed short-circuit current (ISD) can be set separately. The instantaneous triggering of the short-circuit current II is fixed. A Ready LED lights up green when the trigger is operational and flashes orange when an internal fault is detected in the trigger. Another LED starts flashing red when I = 105% IR and lights up permanently red when I > 112% IR. The three different operating modes can be recognized at the position of the toggle (ON = top, OFF = bottom, activated = middle position). A device for locking the switching state in ON or OFF position is integrated and can be used with a commercially available padlock without additional accessories. Via a release key the triggering mechanism can be tested and the main contacts can be opened. A hinged lid with a captive quick screw allows access to the installation room for optional auxiliary contacts and other triggers. Integrated accessories can be identified and identified via a viewing window without opening the hinged cover. The set trigger curve can be tested and documented by an interface for a diagnostic and configuration tool.
