SIRIUS Innovations - SIRIUS 3RU2 thermal overload relays / SIRIUS 3RB3 solid-state overload relays
①
Connection for contactor mounting:
In terms of their electrical and mechanical features
and their design, these pins are perfectly compatible
with the 3RT2 contactors for the direct mounting of
overload relays. Stand-alone assembly is also an
option (in some cases in conjunction with a stand-
alone assembly module).
②
Switch position indicator and TEST function for
wiring:
Indicates a trip and facilitates testing of the wiring.
③
RESET button
A device set to manual RESET can be reset locally
by pressing the RESET button. In addition, an
electronic remote RESET is integrated into the
3RB31.
④
Tripping class setting/internal ground-fault detection:
This rotary switch is used to set the required tripping
class dependent upon the starting conditions and
activate internal ground-fault detection.
⑤
Electronics test (device test):
Enables a test of all major device components and
functions.
⑥
Control circuit terminal (removable):
A screw-type or spring-loaded system can be used to
connect the control circuit terminal.
⑦
Feed-through: Contactor auxiliary switch
⑧
Feed-through: Contactor coil terminal
⑨
Main circuit terminal:
A screw-type or spring-loaded system can be used to
connect the main circuit terminal.
⑩
Selector switch for manual/automatic RESET and
RESET button:
The slide switch is used to choose between manual
and automatic RESET.
