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
For a safety device with single channel, PL level is
determined by MTTF D (mean time between dangerous
failure) emanating from B
B10d:
According the technical data of the switch, the
life duration is determined by maximum switching
operations. Tractel

DANGER: The integrator must take care that
the inductive load could damage the device and
could reduce the electrical life duration. We strongly
recommend not to exceed an apparent power of 80VA
with 48VAC voltage max.
