2.4.4 Disconnecting/isolator module 3RV19 .8-1A
The disconnecting/isolator module is suitable for creating a visible isolating
distance. The isolating connector can only be removed in a deenergized
state. The isolating distance can be secured with padlocks when open.
Disconnecting modules are available for the circuit breakers/MSPs of frame
sizes S0 and S2.
Mounting sequence for
the disconnecting/iso-
lator module and
Transverse auxiliary
contacts
Attention
The disconnecting/isolator module covers the terminal screws of the trans-
verse auxiliary switch. We therefore recommend that you use the lateral
auxiliary switches or that you only install the disconnecting module once the
transverse auxiliary switch has been wired.
Mounting The modules are mounted in the same way for frame sizes S0 and S2. The
following diagrams show you how to mount the disconnecting module.
Example shown for frame size S0 (3RV1928-1A):
