Description

Disconnector module
The disconnector module is mounted on the motor starter protector on the infeed side. The
disconnector module can be used to form a visible isolating distance. To set up the isolating
distance, the plug connector is removed from the enclosure. The isolating plug can only be
removed with the supply disconnected.
The touch-proof isolating point is clearly visible and is secured with a padlock so that the
plug connector cannot be inserted during maintenance work, for example.
The disconnector module is compatible for use with all motor starter protector sizes.
Note
 The disconnector module cannot be used with 3RV27 and 3RV28 circuit breakers.
 The disconnector module covers the connection screws on the transverse auxiliary
switch. Therefore, if you are using the disconnector module, we recommend that you use
the lateral auxiliary switches or wait until the transverse auxiliary switches have been
wired before mounting the disconnector module.
 The disconnector module must not be used in conjunction with the 3-phase busbar
3RV1915.
