Product Description
Ordering Key
RN 1 A 23 A 50
The SOLITRON Solid State
Contactor is designed for
industrial heating and motor
control applications.
The Solid State Contactor is
capable of switching 1-, 2-,
and 3-phase applications
with loads up to 63 A AC51
load and up to 24 A AC53a
load. The Solid State Con-
tactor is designed for DIN-
rail mounting with integrated
heatsink and overvoltage
protection. The heatsink is
moved to the front for optimal
convection cooling in the
panel. Cable ducting system
will not stop the airflow.
The contactor elements are
soldered directly on to the
direct copper bonded sub-
strate (DCB-technology). AC
or DC controlled versions
are available. Built-in LED
status indication for applied
control voltage.
