Product Description
Ordering Key
RN 3 A 40 D 30
The SOLITRON Solid State
Contactor is designed for
industrial heating and motor
control applications. The
Solid State Contactor is
capable of switching 3-phase
loads by using only 2 switch-
ing elements for loads up to
3 x 30 AACrms AC51 load in
Star (excl. Neutral) or Delta
connections. The Solid State
Contactor is designed for
DIN-rail mounting with inte-
grated heatsink and overvolt-
age protection. The heatsink
is moved to the front for opti-
mal convection cooling in the
panel.
The contactor elements are
soldered directly to the direct
copper bonded substrate
(DCB-technology). DC con-
trol versions are availiable.
Built-in LED status indication
for applied control voltage.

Economic switching of inductive and resistive Loads
3-phase 2 pole switching allows a very economical handling of heavy loads which
have to be run in a 3-phase configuration either as a star connection or a delta
connection of the loads. With 2-pole switching and the integration of a contactor
instead of switching all 3-phases a substancial space and cost saving in the panel
can be achieved as one third of the heatsinks can be taken out and also the ven-
tilation of the panel can be reduced.
3-Phase, 2 pole Switching Principle
With SOLITRON RN.3.A.. 3-phase Relays switching with 2-poles and the integra-
tion of a contactor the electric configuration is splitted into a safety part and a
control part. In the safety part the isolation of the lkoad from the mains is assured
by a small contactor mounted in series with the Solid State Relay. The contactor
can be a very economical type as the switching is done by the Solid State Relay.
As the contactors are already switched, when the Solid State Relay is in control
of the power, no burning of the contacts will occur.
