Enclosed Soft Start Trip Class
The MCW Enclosed soft starters ranging from 0.75kW to 15kW come equipped with a standard Trip Class 10 motor breaker, ideal for most light to medium industrial loads. Upon request, they can be upgraded to Trip Class 20, suitable for medium to heavy industrial loads. For this conversion, a larger soft start unit, a Trip Class 20 thermal overload, and a bigger MCB/MCCB will be provided. It's important to note that on certain models, the enclosure size might need to be increased. For further details, feel free to consult with one of our team members.
Trip Class by Application Chart
The MCW Enclosed Soft Starter range is not recommended for applications with extremely heavy starting loads exceeding 20 seconds or for handling very high inertia loads like high inertia fans, centrifuges, or loaded crushers. To address specific application needs, we encourage you to reach out to one of our team members for a tailored discussion.
It's important to note that initiating the MCW Enclosed Soft Starters more frequently than once every 10 minutes will adjust the thermal overload tripping behavior, causing quicker overload trips for a given thermal overload current setting.
Trip Class Explained
At 600% of the maximum current rating of the motor the Trip Class 10 unit will trip in 10 seconds or less, Trip Class 20 will trip in 20 seconds or less, and Trip Class 30 will trip in 30 seconds or less.
Standard model generally kept in stock.
