Star Delta Starters

Electronic soft starters  protect the machine’s mechanical power-transmitting elements during start-up and ramp down, and efficiently guard the network against high inrush peaks through reduced power input. Gentle treatment of network,  motor and load and optimum protection against overload. Comprehensive motor starting solution 0.1 kW to 1200kW.
Dol Starter are ideally suited for usage in remote places, owing to the wide variation in operating parameters. They are available in DOL ( Raja Starters) and Star Delta Starters in Manual as well as ASD type. Keeping in mind the requirement of different bi-relays in different situations, the starters offer only contactors thereby giving the customers the freedom to select  bi-relays (DOL: 15-55kW ; SD:22-55kW)

Digital soft starters - SIRIUS 3RW30/40/44
• Compact design
• Soft starting and smooth ramp-down (soft starting only available for 3RW30)
• Integrated bypass contact system
• Innovative 2-phase “Polarity Balancing” operation
• Energy management, Provision of energy data such as current, voltage and power (3RW44) via bus to higher-level 
  systems
• Current management, Avoidance of current peaks, thus reducing the load on the grid and the mechanical system
• Reduction of control cabinet temperature rises, Depending on technology, lower intrinsic power loss than speed-
  controlled drive systems, and therefore less cooling required, making a more compact design possible. All sizes are 
  equipped with bypass protection, resulting in lower power losses after start-up
