Have you ever experienced a breaker tripping? Introducing the issues with the star-delta system.
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 originally insufficient." You can find detailed information on 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 originally insufficient *For more details, please refer to the PDF materials or feel free to contact us.

Company information
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. To prevent voltage effects on the power supply side, to reduce the capacity of private power generation systems, to prevent damage due to starting stress on the machine side, to avoid starting delays caused by insufficient torque, and as a means of energy saving through frequent repeated starts, we have prepared models suitable for each situation. Furthermore, even in situations where it is difficult to find a solution with the current product lineup, we aim to solve problems by developing and designing the most suitable starter for each specific characteristic through engineering work. Please feel free to consult us; we will not only sell starters but also propose the best methods.
