Operating the devices

Prior to initial commissioning, the rated motor current must
be set on the motor-protective relay by means of the current
dial (a table 3 and table 4, page 34).
Warning!
If the overload relay is installed at a cool location
(e.g. -5 °C) and the motor is installed at a warm motor
location (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.

Reset

The user can select automatic restart "A" or manual reset
"H" on the motor-protective relays ZB12/XTOB...BC1 and
ZB32/XTOB...CC1 by means of the Reset selector button.

Figure 10: Switching options of the reset selector button
The factory set position "H" on the motor-protective relay
prevents automatic restarts. In position "H", the relay must
be reset manually after it has tripped by pressing the selector
button.
