Hager HNW631JR Circuit breaker 1 pc(s) Adjustment range (amperage): 630 A (max) Piece

Power switch h3+ P630 LSI 4P4D N0-50-100% 630A 40kA FTC. This compact circuit breaker complies with DIN EN 60947-2 and protects the electrical system and networks against overload and short circuit. The trigger curve of the electronic release can be set via rotary locking switch. The triggers for the overload current (IR), the short-time delayed short-circuit current (ISD) and the instantaneous short-circuit protection (II) as well as the time delay tr on overload and the time delay tsd for short-term delayed short-circuit triggering are separately adjustable. In addition, the tripping curve can be adapted proportionally by means of an selectable I²t function between the short-circuit currents II and ISD and the short-time delayed and instantaneous tripping time. The Ready LED lights up green when the trigger is operational and flashes orange when an internal fault is detected in the trigger. The overcurrent indicator LED begins to flash red when I = 105% IR and is lit red permanently when I > 112% IR. Another LED signals the overheating in the triggering unit. The lamp flashes red when the internally exceeds 105°C. The three different operating modes can be recognized at the position of the toggle (ON = top, OFF = bottom, activated = middle position). A device for locking the switching state in ON or OFF position is integrated and can be used with a commercially available padlock without additional accessories. Via a release key the triggering mechanism can be tested and the main contacts can be opened. A hinged lid with a captive quick screw allows access to the installation room for optional auxiliary contacts and other triggers. Integrated accessories can be identified and identified via a viewing window without opening the hinged cover. A potential-free alarm contact for the switch-off pre-warning in the event of a switch-off due to overload is integrated as standard. This is done at I >
