3RT, 3TB, 3TF Contactors for Switching Motors
3RT12 vacuum contactors, 3-pole, 110 ... 250 kW
■
Overview
• 3RT12 vacuum contactors for switching motors
Operating mechanism types
Two types of solenoid operation are available:
• Conventional operating mechanism, version 3RT12 ..-.A
• Solid-state operating mechanism, version 3RT12 ..-.N
UC operation
The contactors can be operated with AC (40 to 60 Hz) as well as
with DC.
Withdrawable coils
For simple coil replacement, e.g. if the application is replaced,
the magnetic coil can be pulled out upwards after the release
mechanism has been actuated and can be replaced by any
other coil of the same size.
Auxiliary contact complement
The contactors can be fitted with up to 8 laterally mounted
auxiliary contacts (identical auxiliary switch blocks from S0 to
S12). Of these, no more than 4 are permitted to be NC contacts.
