Hager HEJ251DR h3 x630 TM ADJ 4P4D 250A 70kA circuit breaker

Circuit breaker h3 x630 TM ADJ 4P4D N0-100% 250A 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 thermal release for the overload current (Ir) and the magnetic release for the instantaneous short circuit current (Ii) can be set separately. The three different operating states can be identified by the position of the knob (ON = top, OFF = bottom, triggered = 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 release 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 releases. Integrated accessories can be seen and identified via the viewing window without opening the hinged lid.
