Why is Stardelta not acceptable?
Have you ever experienced a breaker trip? Introducing the issues with Star Delta.
To avoid direct connection troubles, the star-delta method is generally used, but there are issues here as well. Has the breaker ever tripped? The breaker can trip during "the switch from star to delta" and "when the starting torque is insufficient." You can find detailed information about each pattern in the related links. 【Why does the breaker trip?】 ■Reason 1: When switching from star to delta ■Reason 2: When the starting torque is insufficient *For more details, please refer to the PDF materials or feel free to contact us.

We are the only manufacturer in Japan specializing in starters, researching, developing, and producing soft starters, proposing solutions to various troubles that occur when starting stopped motors and machines by reviewing the starting methods. As measures to prevent voltage drops on the power supply side, to reduce the capacity of private power generation systems, to prevent damage caused by stress during machine startup, to avoid startup congestion due to insufficient torque, and as energy-saving measures for frequent repeated startups, we have prepared models tailored to each situation. Furthermore, even in situations where it is difficult to find a solution with the current product lineup, we aim to resolve issues by developing and designing the optimal starter for the specific characteristics through engineering work as needed. Please feel free to consult us; we will not only sell starters but also propose the best solutions.
