Mounting 3RR2 current monitoring relay

Mounting options
3RR2 current monitoring relays are matched to 3RT2 contactors and 3RF34 (size S0) solid-
state contactors in terms of their electrical and mechanical features. As a result, direct
mounting can be achieved easily.
Alternatively, the devices can also be installed individually in the case of stand-alone
assembly or if a 3RU2 / 3RB3 overload relay is being used at the same time. The
accessories required for separate mounting are described in Chapter "Terminal support for
stand-alone assembly (Page 324)."
Minimum clearance
The following minimum clearances from grounded and live parts must be complied with
when installing the 3RR2 monitoring relay:
● At the side: 6 mm
● Forward (on front): 6 mm
Mounting position
It can be mounted in any position.
