Safety considerations:
This device can be set for 2 overload trigger points which can be set separately. For a safety function each of them
is a single channel considered as a «well tried component» by Tractel
Achieving a PL required for a safety function:
For a safety device with single channel, PL level is
determinedby MTTF D (meantimebetweendangerous
failure)emaningfromB

According the technical datas of the switch, the
life duration is determined by maximum switching
