Contactors with solid-state operating mechanism
The magnetic coil is supplied selectively with the power required
for reliable switching and holding by series-connected control
electronics.
• Wide voltage range for the control supply voltage U
• Extended operating range 0.7 to 1.25 x U
• Bridging temporary voltage dips:
• Defined ON and OFF thresholds:
• Low control power consumption when closing and in the
Electromagnetic compatibility (EMC)
The contactors with solid-state operating mechanism comply
with the requirements for operation in industrial installations.
• Interference immunity
• Emitted interference
Note:
When used with converters, the control cables must be routed
separately from the load cables of the converter.
Indication of remaining lifetime (RLT)
Main contactor contacts are working parts which must be
replaced in good time when the end of their service life has been
reached. The degree of contact erosion and thus the electrical
endurance (= number of operating cycles) depends on the
loading, utilization category, duty type, etc. Routine
checks/visual inspections by the service personnel are needed
in order to monitor the state of the main contacts. The "remaining
lifetime indication" function takes over this task. It does not count
the number of operating cycles – which does not provide
information about contact erosion – but instead electronically
identifies, evaluates and stores the actual progress of erosion of
each one of the three main contacts, and outputs a warning
when specified limits are reached. The stored data are not lost
even if the control supply voltage for A1/A2 fails. After
replacement of the main contacts, measurement the remaining
lifetime must be reset using the "RESET" button (hold down
RESET button for about 2 seconds using a pen or similar tool).
Compared with the conventional operating mechanism, the
solid-state operating mechanism covers an even broader
range of control supply voltages used worldwide within one
coil variant. For example, the coil for UC 200 to 277 V

reliably, for the most common control supply voltages of 24,
110 and 230 V.
Control voltage failures dipping to 0 V (at A1/A2) are bridged
for up to approx. 25 ms to avoid unintentional tripping.
For voltages of ˜ 0.8 x U
reliably switch the contactor ON, and as of ˆ 0.5 x U
reliably switched off. The differential travel in the switching
thresholds prevents the main contacts from chattering as well
as increased wear or welding when operated in weak,
unstable networks. This also prevents thermal overloading of
the contactor coil if the voltage applied is too low (contactor
does not close properly and is continuously operated with
overexcitation).
