Caution
The solid-state time relay block with a semiconductor output
(3RT1926-2C, -2D) must not be used for 3RT104 contactors of frame size S3
≤
with U 42 V because the coil current used for the output semiconductor
S
is too high.
The solid-state time relay block must not be attached to the lower coil con-
nections.
