The standard draws a distinction between two coordination types, known as coordination type 1 and coordination type 2.
They describe what happens at a short circuit and the device status after a short circuit. In both coordination types, the short circuit to be dealt with is reliably disconnected. There must be no damage to systems or injury to persons.
The differences lie only in the degree to which the device is damaged after the short circuit.

Coordination type 1:
The load feeder (e.g. motor starter) can be inoperable after each short-circuit.
Damage to the contactor and the overload relay is permissible and it is only possible to continue operation after defective devices have been repaired or replaced.

Coordination type 2:
After a short-circuit, there must be no damage to the load feeder devices.
However, the contactor contacts can weld if they can be easily separated again without distorting the contact pieces.
