Hager HMT041GR h3+ P250 4P4D 40A 50kA circuit breaker

Circuit breaker h3+ P250 LSnI 4P4D N0-50-100% 40A 50kA 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. The neutral conductor protection can be set to the OFF position, 50% of Ir and Isd or 100% of Ir and Isd using a control. The time delay remains the same as for tr and tsd. 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 to flash 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 toggle (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 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 recognized 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.
