Compact Starters


200V - 575V 3~
18-200A / 5-150hp

CSX Soft Start

Our CSX series has one of the smallest foot prints available, and includes a built-in bypass contactors, which allow significant space savings versus our competitors; ideal for MCC applications. Built-in bypass contactor allows the use of smaller, non-ventilated enclosures on all manufactured packages. The CSXi series includes all of the functionality of the CSX, with the addition of motor protection and current limit/current ramp starting modes.




Digital Starters


200V ~ 690V 3~
23A-1600A / 5-1300hp

EMX Soft Start

Our EMX3 series has one of the smallest foot prints available, and includes the world's first soft starter to control acceleration. We call it Adaptive Acceleration control or XLR-8. More control means smarter starts and smoother stops that reduce downtime and eliminate water hammer problems. The EMX3 meets the needs of specific applications including: Pumping (e.g. high head applications), Compressors (optimising load control), Bandsaws (easy blade alignment), Irrigators (built-in timer). For applications requiring precise control of motor start current the EMX3 offers a choice of Constant Current or Current Ramp start modes.


200-690V 3~
18A-1574A / 3-1300hp

IMS2 Soft Start

Saftronics’ IMS2 Series soft starters are a total motor starting solution, combining high-level functionality with flexibility and ease of use. In simple installations, commissioning requires only one parameter to be set. For advanced applications, an extensive range of functions makes the IMS2 suitable for nearly all motor starting and control requirements. The IMS2 offers a choice of soft start and soft stop profiles to ensure optimum control for all load types. The unique torque control system gives more linear acceleration than standard constant current, and a special pump control function reduces water hammer. In addition to leading edge soft start and soft stop, the IMS2 incorporates advanced motor and load protection features. IMS2 minimizes installation time and costs and ensures that motors can be operated with confidence.

DY5 Electronic Motor Brake

200-600V 3~

DY5 brake

The DY5 unit is an electronic AC motor brake that can be applied to any starter. Installation is simple and fast. Only four power wires are needed, plus five interconnecting leads to the existing starter.
