SIRIUS 3RV1 Mountable Accessories
Siemens 3RV1 circuit breakers have three main contact elements
In order to achieve maximum flexibility, signaling switches, auxiliary switches and isolator modules can be easily fitted to the switches without the use of any tools according to requirements
Signaling Switches for sizes S0, S2, and S3
One contact system always signals tripping irrespective of whether this was caused by a short circuit, an overload or an auxiliary release
The other contact system only switches in the event of a short circuit
There is no signaling as a result of switching off with the handle
One signaling switch can be mounted on the left side of each circuit breaker
In order to be able to switch on the circuit breaker again after a short circuit, the signaling switch must be reset manually after the error cause has been eliminated
Auxiliary Switch
For remote controlled tripping of the circuit breaker, the release coil should only be energized for short periods
Isolator Module for sizes S0 and S2
The supply cable is connected to the circuit breaker through the isolator module
The plug can only be unplugged when the circuit breaker is open and isolates all 3 poles from the network
The shock protected isolation point is clearly visible and secured with a padlock to prevent reinsertion of the plug
Isolator modules can be mounted to the upper terminal end of the circuit breaker.
