4.9.13 3RV2917 infeed system
4.9.13.1 Description
Overview
The 3RV29 infeed system provides a convenient means of feeding in and distributing power
for a group of several motor starter protectors or complete load feeders with screw and
spring-loaded connections in size S00 and S0 (exception: this system cannot be used with
3RV21 motor starter protectors and 3RV27 and 3RV28 circuit breakers). .
The system is based on a basic module complete with a lateral infeed (3-phase busbar with
infeed). This infeed with spring-loaded connections is attached on the left or right depending
on the version and can be fed in with a maximum conductor cross-section of 25 mm2 (with
end sleeve). A basic module has two slots onto each of which a motor starter protector can
be snapped.
Expansion modules (3-phase busbars for system expansion) are available for expanding the
system. An expansion plug is used to connect the individual modules.
The electrical connection between the 3-phase busbars and the motor starter protectors is
established using connectors. The complete system can be installed on a TH 35 DIN rail
conforming to DIN EN 60715 and can be expanded at will up to the maximum current
carrying capacity of 63 A.
The simple and time-saving plug-in connections mean that the system can be set up easily
and in next to no time. The lateral infeed means that the system does not take up as much
space in the control cabinet either. The additional overall height required for the infeed is just
30 mm. The option to have the infeed on both sides maximizes flexibility where the
configuration of the control cabinet is concerned: Infeed on left-hand or right-hand side as
well as infeed on one side and outfeed on the other side to supply further loads with power
are all possible. As well as the integration of SIRIUS motor starter protectors, a terminal
block with spring-loaded-connections in conjunction with a DIN rail also supports the
integration of 1-/2-/3-phase components such as 5SY miniature circuit breakers or SIRIUS
relay components.
