Construction characteristics
Low current breaking for DC circuits 2
R63 … R2100 contactors
If the breaking current is lower than 50 % of the contactor
rating, permanent magnet must be added. Please consult us.
Refer to blowout code table in DC circuit switching
Control circuit The electro-magnet is built with a magnetic circuit and a coil.
It is mounted on the right side or on the frame center, in stan-
Rectifier dard. It can be mounted on the left side on request.
Economy resistor AC control circuit supply:
RR electro-magnet
The coil is fed from an AC supply via a rectifier and an
economy resistor.
The control supply frequency is 50/60 Hz in standard.
For others frequencies, please consult us.
DC control circuit supply:
RE electro-magnet
The coil is fed from a DC supply via an economy resistor.
Latching version
(see following pages)
Magnetical latching for R63 … R200
Mechanical latching for R500 … R5100
Low consumption coil for R63 … R500 contactors (on request)
–– Up to 6 times less in control power consumption at holding
–– Reduced width up to 15 % compared to standard R contactors
–– Control voltage available:
--24…440 V 50 / 60 Hz
--24…250 V DC
–– Example of type: IORE63..-LC.
Principle A varistor and a lagging contact for holding winding
insertion are factory mounted.
Uc
A1 A2 Only a part of the winding (B1) is energized at closing.
After opening the NC contact, the complete coil (B1 +
B2 = Holding B2) is used for contactor holding.
Varistor
B1 = Pull-in
