Hager HMS161JC h3+ P160 4P4D 160A 50kA circuit breaker

Circuit breaker h3+ P160 LSI 4P4D N0-50-100% 160A 50kA CTC. 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 elements for the overload current (Ir), the short-time delayed short-circuit current (Isd) and the undelayed short-circuit protection (Ii) as well as the time delay tr for overload and the time delay tsd for short-time delayed short-circuit tripping can be set separately. In addition, the tripping curve can be adjusted inversely proportionally using an activatable I²t function between the short-circuit currents Ii and Isd and the short-time delayed and undelayed tripping time. 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. The ready LED lights up green when the release is ready for operation and flashes orange when an internal error is detected in the release. The LED for the overcurrent indicator starts flashing red when I = 105% Ir and lights up red continuously when I > 112% Ir. Another LED signals the overtemperature in the release unit. This lights up red when 105°C is exceeded internally. 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 release button can be used to test the release mechanism and open the main contacts. 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 the viewing window without opening the hinged cover. A potential-free alarm contact for the switch-off warning in the event of a risk of switch-off due to overload is integrated as standard. This is closed when I > 90% Ir. This is indicated by an additional LED. It lights up orange when the contact is closed. The set tripping curve can be tested and documented using an interface for a diagnostic and configuration tool.
