3RT10 contactors, 3-pole, sizes S6 to S12, > 45 to 250 kW
• 3RT10, contactors for switching motors,
• 3RT12, vacuum contactors for switching motors,
• 3RT14, contactors for AC-1 applications
Operating mechanism types
Two types of solenoid operation are available:
· Conventional operating mechanism
· Solid-state operating mechanism (with 3 performance levels)
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 auxiliary contacts (identical auxiliary switch blocks from S0 to S12). Of these, no more than 4 are permitted to be NC contacts.
3RT10 and 3RT14 contactors:
Auxiliary contacts mounted laterally and on front
3RT12 vacuum contactors:
Auxiliary contacts mounted laterally
