Maximum expansion
The maximum expansion of the 3RV2 motor starter protector is one transverse auxiliary
switch, one lateral auxiliary switch with 2 contacts, one signaling switch, and one auxiliary
release.
The lateral auxiliary switch 2 NO + 2 NC can also be used as an alternative to a transverse
auxiliary switch and a lateral auxiliary switch with 2 contacts. However, in this case it will not
be possible to add a signaling switch. Accordingly, a maximum of 4 auxiliary contacts with
auxiliary switches may be mounted on each motor starter protector.
Possible combinations
The following auxiliary/signaling switch and auxiliary switch combinations are possible:
● The lateral auxiliary switch must be mounted to the left of the signaling switch.
● Transverse and lateral auxiliary switches can be combined.
● A maximum of 4 auxiliary contacts may be added.
● One auxiliary release can be mounted on the right of each motor starter protector.
● The signaling switch must be selected before the auxiliary switch.
● Once a signaling switch has been selected, only one lateral auxiliary switch with 2
contacts can be selected. It is not possible to select the lateral auxiliary switch with 4
contacts.
● The total number of auxiliary switch contacts must not exceed 4.
