VS II 400-12 soft starter

The soft starter VersiStart II [3,5 – 16 A] enables controlled, gentle start-up of asynchronous motors and significantly reduces mechanical and electrical loads. The device works microcontroller-controlled, compact and reliable – ideal for pumps, fans and conveyor technology. Thanks to its easy installation on the 35 mm standard rail, the VersiStart II is a cost-effective alternative to the classic star triangle switch.

Note:

When using IE3-Motoren, higher starting and braking currents must be taken into account. We recommend that soft starters and brake devices each have a higher power level.
