Standard contact devices with magnetic pressure increase
Can be used under virtually all operating conditions. They are very largely insensitive to
vibration. The contact pin holder of the setting pointer is fitted with an adjustable magnet
which attracts the contact arm just before the pre-set level is reached. This avoids arcing
and scorching of the contact pin. Since in this design the force of the magnet applies during
the switching operation, the setting pointer must be adjusted forwards or backwards by the
resultant difference in the switching level, about 3-6% of the final value on the scale. This
difference can be varied by the adjusting screw on top of the magnet.
Switching capacity
These contact devices are suitable for d.c. or a.c. currents up to 380 V and switching capac
ities up to 30 VA. The current to be switched should not exceed 1A. (A special design can
be supplied for switching capacities up to 50 VA). If required the contact devices can be
supplied in an intrinsically safe design, i.e. suitable for connection to intrinsically safe re
lays.
