Smart motorstarter
UG 9256

The smart motorstarter function is a softstart, reversal and protection of 3-phase asynchronous motors. Overcurrent is detected when the set current is exceeded longer than 2 sec. Direction reversal takes place via relay switching. The relays are de-energised at this. This ensures a long service life.

Advantages
. Up to 6 function in one unit
- Reversing anticlockwise
- Reversing clockwise
- Softstart
- Softstop
- Current monitoring or motor protection
- Galvanic separation via forcibly guided contacts contact distance min. 0.5 mm
. 80 % less space
. Simple and time-saving commissioning as well as user-friendly operation through setting via potentiometers on absolute scales
. Blocking protection
. Hybrid relay combines benefits of relay technology with non-wearing semiconductor technology
. High availablility by
- Temperature monitoring of semiconductors
- High withstand voltage up to 1500 V
- Load free relay reversing function
. As option with disabling current monitoring
