Product Description
Ordering Key
This product is designed in
such a way as to replace elec-
tro-mechanical contactors,
especially when switching is
frequent. It has an integrated
heatsink and over-voltage pro-
tection. The heatsink is
moved to the back for optimal
space saving in the panel and
easy wire mounting at the front
of the relay.
The relay with antiparallel
thyristor output can be used
for resistive and inductive
loads.
RJT3A comes with 3 indepen-
dently controlled poles, with
three LEDs to indicate status
of each control input.
Each zero switching relay
switches ON when the sinu-
soidal curve crosses zero and
switches OFF when the cur-
rent crosses zero.

Application of DC voltage across ter-
minals A1-A4 will activate pole L1-
T1. The top green LED indicates the
status of the control input across ter-
minals A1-A4.
Application of DC voltage across ter-
minals A2-A4 will activate pole L2-
T2. The middle green LED indicates
the status of the input voltage across
terminals A2-A4.
Application of DC voltage across A3-
A4 will activate pole L3-T3. The bot-
tom green LED indicates the status
of the input voltage across terminals
A3-A4.
For 3-Phase control, A1, A2 and A3
can be connected together to switch
all three poles simultaneously.
