Overview
SIRIUS 3RT19 timing relay
SIRIUS 3RT19 electronic timing relays for mounting onto
contactors with:
•
1 NO and 1 NC or 2 NO
• Monofunction
• Monovoltage
•
Single or selectable time setting ranges
Simply by being plugged in place, the SIRIUS 3RT19 timing re-
lays enable different functionalities required for the assembly of
starters to be realized in the feeder. At the same time the timing
relays for mounting onto contactors reduce the wiring work re-
quired within the feeder and save space in the control cabinet.
A protection circuit (varistor) is integrated in each module.
The electronic timing relay with semiconductor output uses two
plug-in contacts to actuate the contactor underneath by means
of a semiconductor after the set time has elapsed.
The time-delay auxiliary switch is supplied with power directly by
two plug-in contacts through the coil terminals of the contactor,
in parallel with A1/A2.
The switching state feedback is performed by a mechanical
switching state indicator (plunger).
