Control auxiliaries
These auxiliaries can perform a great variety of functions:
from the simplest (signalling, timer, illumination delay, etc.);
to the most sophisticated (centralised multi-level control, step-by-step control, etc.).
Moreover, some auxiliaries make it possible to overcome electrical disturbance which may detract from satisfactory switching operation.
Schneider Electric has the most comprehensive and coherent product offering in the market. All the auxiliaries in a family (modular contactor or impulse relay) are compatible with all the devices in that family.
They are very easy to install thanks to their integral mounting clips which simultaneously provide electrical and mechanical connections
