Low space requirements
3SW68 devices are very compact thus require very little space for installation. Frame A devices (up to 1600 A) fit into a 400 mm wide switchgear panel.Frame B,C,D devices (up to 6300 A) are the smallest of their kind and with their smallest construction width fits into a 800 mm wide switchgear panel.

Indication1. RESET button It pops up when fault tripping or test tripping. The circuit breaker can be switched on only when the button is pressed down. Meanwhile, the fault indicator resets.2. LCD display3. Fault and alarm RESET key4. FAULT/ALARM LED indicator The indicator is out when normal working; it flashes quickly when maintenance; it turns on in red when alarm.5. NORMAL LED indicator It flashes in green always when the controller is power on and under normal working.6. LED curve Red LED indicators are equipped in the curve. The corresponding indicator flashes to indicate the fault reason when fault tripping. The corresponding indicator remains lit to indicate the current setting when protection settings.7. Test port A 16-pin test port is available on the bottom of front panel for plug-in portable power supply or inspection unit.
Keyboard 8. Function key 1 – Measurement: For measuring (In password input interface, the LEFT key) Press to enter the measurement default menu to measure current “I”, voltage “U’, frequency “F”, power “P”, energy “E”, and harmonic “H”.9. Function key 2 – Settings: For system parameter settings (In password input interface, the RIGHT key) Press to enter the setting default menu to set “Clock settings”, “Meter settings”, “Test & Lock”, “Communication settings”, “I/O settings”.10. Function key 3 – Protections: For protection parameter settings Press to set the parameters of “Current protection”, “Load monitor”, “Voltage protection”, and “Other protections”. 11. Function key 4 – Information: For history record and maintenance Press to check “Current alarm”, “Operation times”, “Contact wear”, “Product information”, “Tripping record”, “Alarm record”, “Transposition record”.12. UP – To move up or change the parameters upwards13. DOWN – To move down or change the parameters downwards.14. Esc – To exit and return to previous menu or cancel the current setting selection.15.

Illustration1.The corresponding circuit breakers in the diagram are switched off and no energy stored. The controller indicates no fault2.The dotted line part shall be connected by user, the picture is for reference only.3. 1#, 2# terminal power source must be prepared when the main loop current is 0.4 In. The DC24V、AC230VAC or 400V power can be connected depending on controller power type. The power then connects with DC 110VD and C220V after converted by power module.4. Q, X, F, M connects different control power sources depending on respective voltage specifications. Please note X, F are short-time duty components, the electrified time should not exceed 4 seconds.5.37# terminal directly connects power source (see the picture) (automatic pre-energy storage). It can also connect power source after serially connecting the normally open button (Manual pre-energy storage).6.The three position signal sampling from the draw-out base communication module should be processed by optical coupling isolation.7. The outdoor terminal which fixed on the drawing frame of breaker, wiring connection is according to picture 2; the terminal which fixed in internal breaker, wiring connection is according to picture 3.

Under-voltage releaseThe under-voltage release consists of release coil and control units.The under-voltage release works in two ways: instantaneous operation and delayed operation.Operational accessory
Note: If the delay time of under-voltage delayed release is above 3 second, it is the special specification
Auxiliary contactStandard configuration we provided to client is four convertible contacts. The six convertible contacts, four normally open, four normally closed contacts or six normally open, normally closed contacts are also available for special applications
