SDS Trip Class

The MCW 75kW star delta starters are fitted with a Trip Class 20 thermal overload relay as standard which is suitable for the majority of light to medium industrial type load applications. As an option the star delta starters can be converted to trip class 20 (medium to heavy industrial loads) at time of purchase. This involves a larger contactor unit and a trip class 20 thermal overload. The trip class 20, OC SDS will come supplied with the motor thermal overload separate to the contactor arrangement and housed in a standalone mounting base.

The MCW star delta starter range is not suitable for applications that have a very heavy load on start that takes greater than 20s to start or very high inertia loads such as high inertia fans, centrifuges or loaded crushers.

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.
