Hager HEJ631GR h3 x630 LSnI 4P4D 630A 70kA circuit breaker

Circuit breaker h3 x630 LSnI 4P4D N0-50-100% 630A 70kA FTC. 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 using a rotary latching switch. The tripping for the overload current (Ir) and the short-time delayed short-circuit current (Isd) can be set separately. The instantaneous tripping for the short-circuit current Ii is fixed. A standby LED lights up green when the trip is ready for operation and flashes orange when an internal error is detected in the trip. Another LED starts flashing red when I = 105% Ir and lights up red continuously when I > 112% Ir. The three different operating states can be recognized by the position of the knob (ON = top, OFF = bottom, tripped = 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 release 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 seen and identified via a viewing window without opening the hinged cover. The set tripping curve can be tested and documented using an interface for a diagnostic and configuration tool.
