HAND DRIVES Description The hand drive makes possible to govern the circuit-breaker by rotating the lever, e.g. to switch machines on and off. When a circuit breaker is ordered along with the hand drive, this unit will be installed in the circuit breaker by manufacturer and supplied complete. The hand drive with the so called adjustable lever is provided with an extra supply of an extension shaft and a bearing with an operating lever The hand drive makes it possible to control the circuit breaker: a) from the front panel of the circuit breaker (Fig. 1) - BA511*33-*****86 design - for dimensions, see page 161 b) through the switchgear door (Fig. 2) - BA511*33-*****861 design - for dimensions, see page 161 The hand drive bearing is attached to the switchgear door and provides protection IP55. Fig. 1 - Front hand drive Safety improvement for operators tending to electric equipment Hand drive lever makes it possible to lock up the circuit breaker in position switched off manually by means of three padlocks with the shank diameter up to 6 mm.
