The insulating stop is for contactors with spring-loaded connections. In the case of
conductors with a small conductor cross-section (≤ 1mm
2
), it ensures that the conductor
insulation is not clamped with the rest of the cable. An insulating stop unit comprises 5 pairs
of terminals which can be separated. The diagram below illustrates an example of how the
the 3RT2916-4JA02 insulating stop can be used on a size S00 basic device.
