SIRIUS 3RT10 contactors,
3-pole, 3 ... 250 kW

Version 3RT1. . .-.P: for 24 V DC PLC output or
PLC relay output, with remaining lifetime indicator (RLT).
To supply the solenoid and the remaining lifetime indicator with
power, the control supply voltage U
s
must be connected to ter-
minals A1/A2 of the laterally mounted solid-state module. The
control inputs of the contactor are connected to a 7-pole plug-in
connection; the screwless spring-type connection is part of the
scope of supply.
• The "Remaining Lifetime RLT
" status signal is available at ter-
minals R1/R2 through a floating relay contact (hard gold-
plated, enclosed) and can be input to SIMOCODE, PLC or
other devices for processing, for example.
Permissible current-carrying capacity of the R1/R2 relay out-
put:
- I

/AC-15/24 to 230 V: 3 A
- I

/DC-13/24 V: 1 A
• LED displays
The following states are indicated by means of LEDs on the
laterally mounted solid-state module:
- Contactor ON (energized state): green LED ("ON")
- Indication of remaining lifetime
2 control options:
7 Contactor control without a coupling link directly through a 24
V DC/≥ 30 mA PLC output (IEC 61131-2) by way of terminals
IN+/IN-.
Possibility of switching from automatic control to local control by
way of terminals H1/H2, i.e. automatic control through PLC or SI-
MOCODE/PROFIBUS DP can be deactivated e.g. at start-up or
in the event of a fault and the contactor can be controlled man-
ually.
7 Contactor control through relay outputs at connections H1/H2,
e.g. by
- PLC or
-SIMOCODE
Contact loading: U
s
/approx. 5 mA.
When operated through SIMOCODE, a communication link to
PROFIBUS DP is also provided.
Order No. scheme
