Types of coordination
The IEC 60947-4-1 (VDE 0660 Part 102) standard distinguishes between two types of
coordination referred to as coordination type "1" and coordination type "2". The short circuit
that needs to be dealt with is cleared reliably and safely with both types of coordination; the
only differences are in the extent of the damage sustained by the device following a short
circuit.
