Type of coordination 1 or 2
When selecting the combinations, in many cases, either coordination type 1 or 2 can be
selected. According to IEC 60947-4-1, the coordination type defines the permissible degree
of damage for a device following a short-circuit.
• Type of coordination 1:
After a short-circuit, it is permissible for the starter to be inoperative, in particular, damage to the
contactor, solid-state switching devices and overload relay is permissible.
• Type of coordination 2:
The starter is still operative. There must be no signs of damage to the devices, with the exception
of slightly welded contactor contacts if these can be easily separated again without any noticeable
deformation.
In both cases, the short-circuit is reliably and safely cleared. Combinations of coordination
type 2 are therefore of a higher quality and are rapidly available for reuse after a short-circuit.
In the case of solid-state switching devices, the same applies as for type of coordination 2,
that the short-circuit is cleared without any damage to the power semiconductors.
Combinations of coordination type 1 are generally the more favorably priced solution.
Combinations of coordination type 2 automatically fulfill the requirements of coordination
type 1.
Tests
All of the specified combinations are tested in compliance with IEC 60947-4-1.
