HTI+H/S

* Features: Combined auxiliary and signal contact for the external displayThe HTI+H/S combined auxiliary and signal contact is used for electrical signaling of the operating state of the high performance Hti+.The H auxiliary contact always switches simultaneously with the live conductor contact and detect the following forms of tripping:− Manual switch on/off− Tripping due to thermal overload− Tripping due to magnetic overload (short-circuit)− Tripping by Shunt trip or UndervoltageThe S signal contact detects the following forms of tripping of the high performance MCB:− Tripping due to thermal overload− Tripping due to magnetic overload (short-circuit)− Tripping by Shunt trip or UndervoltageMode of function of the S reset buttonThe reset button, which can be used at will, resets the S signal contact after a tripping. The high performance MCB is switched on independent of the state of the S signal contact.Mode of function of the H changeover contact− Off position of the high performance MCB Contact 11–12 closed− On position of the high performance MCB Contact 11–14 closedMode of function of the S changeover contact− No S tripping Contact 95–96 closed− S tripping Contact 95–98 closed.
