Before using the overload relay for the first time, the rated current must be
set using a current setting dial on the relay (￫ table 3, page 30 and table 4,
page 31).
CAUTION

If the overload relay is installed at a cool location (e.g. -5 °C) und
the motor is installed at a warm motor installation site (e.g.
40 °C), it is possible that there will be a delayed release during
an overload if the devices are operated in the lower current
setting range.
The user can select automatic restart "A" or manual reset "H" on the
overload relays ZB12-.../XTOB...BC1 and ZB32-.../XTOB...CC1 by means of
