Contactors in Safety Circuits
Contactors are an integral part of safety applications. Schneider Electric offers a wide variety
of contactors which are suitable for use in safety applications due to mechanically linked power
contacts and mirror contacts.
A number of standards have been published in recent years that use the concept of functional
safety. Examples include IEC 61508, IEC 62061, IEC 61511, ISO 13849-1, and IEC 61800-5-2
which have all been adopted in Europe and published as ENs. Functional safety is a relatively
recent concept that replaces the old `Categories' of behavior under fault conditions that were
defi ned in EN 954-1, and were often mistakenly described as `Safety Categories'.
Now that EN 954-1 is withdrawn, the available alternatives are EN 62061 and EN ISO 13849-1.
The performance of each safety function is specified as either a SIL (Safety Integrity Level) in
the case of EN 62061 or PL (Performance Level) in the case of EN ISO 13849-1. In both cases
the architecture of the control circuit which delivers the safety function is a factor, but unlike
EN 954-1 these new standards require consideration of the reliability of the selected components.
In the past there has been a tendency for components specified to a high category of EN 954-1
to be chosen instead of components that have a lower category, but might actually have more
suitable functions. This might be as a result of the misconception that the categories are
hierarchical such that for example, category 3 is always “better” than category 2 and so on.
Functional safety standards are intended to encourage designers to focus more on the functions
that are necessary to reduce each individual risk, and what performance is required for each
function, rather than simply relying on particular components.
