Definition of Type 2 short-circuit coordination per UL508• The contactor or starter must not endanger
persons or plant in the event of a short-circuit.• The contactor or starter must be suitable for
continuous use.• No damage to the overload relay or other parts
may occur with the exception of welding of the contactor or starter contacts if these can be easily separated without appreciable deformation (such aswithascrewdriver).
In the event of a short-circuit, fast-opening, strong current-limiting KT7 motor protectors make it possible to build economical, fully short-circuit coordinated starter combinations in accordance with UL508E, Type 2 coordination.
