UA16 … UA30 3-pole contactors for capacitor switching

12.5 to 27.5 kvar - Peak current Î ≤ 100 times the rms current
AC operated

Description
UA contactors can be used for the switching of capacitor banks whose inrush current peaks are less than or
equal to 100 times nominal rms current.
The capacitors must be discharged (maximum residual voltage at terminals ≤ 50 V) before being re-energized
1SBC591694F0304 when the contactors are making.
These contactors are of the block type design with:
– 3 main poles and 1 built-in auxiliary contact
– control circuit: AC operated
UA16-30-10
– add-on auxiliary contact blocks for front or side mounting and a wide range of accessories.
