Hager HEJ631GR

Circuit breaker h3 x630 LSnI 4P4D N0-50-100% 630A 70kA FTC. The compact circuit breaker complies with DIN EN 60947-2 and protects electrical installations and networks from overload and short circuits. The tripping curve of the electronic release can be adjusted using a rotary switch. The triggers for overload current (Ir) and short-circuit current with time delay (Isd) can be set separately. The instantaneous trip for short-circuit current (Ii) is fixed. A standby LED lights up green when the trigger is ready for operation and blinks orange when an internal fault in the trigger is detected. Another LED starts blinking red when I = 105% Ir and lights up continuously red when I > 112% Ir. The position of the knob indicates the three different operating states (ON = top, OFF = bottom, tripped = middle position). A device for locking the switch state in the ON or OFF position is integrated and can be used with a standard padlock without additional accessories. A test button allows the tripping mechanism to be tested and the main contacts to be opened. A hinged cover with a captive quick screw provides access to the installation space for optional auxiliary contacts and other triggers. Integrated accessories can be seen and identified through a viewing window without opening the hinged cover. Through an interface for a diagnostic and configuration tool, the set tripping curve can be tested and documented.
