Enclosed Star Delta Starter Trip Class

The MCW Enclosed Star-Delta starters come equipped with a standard Trip Class 10 thermal overload relay, ideal for most light to medium industrial load applications. For medium to heavy industrial loads, an upgrade to Trip Class 20 is available at the time of purchase. This upgrade may require a larger star-delta starter contactor setup, a Trip Class 20 thermal overload, and an upgraded MCB/MCCB.

Please note that for some models, upgrading to Trip Class 20 may result in an increase in enclosure size.

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.
