Open Chassis Star Delta Starter Trip Class
This MCW open chassis star-delta starter is fitted as standard with a Trip Class 20 thermal overload relay, suitable for most medium to heavy industrial load applications.
Where a Trip Class 20 relay is selected, the starter may require a larger contactor set and is supplied with the thermal overload relay mounted separately from the main contactor arrangement, housed on a mounting base.
Trip Class by Application Chart
The MCW Enclosed Start Delta 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 Star Delta 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.
