Product Description
-
A30..RA 3-pole contactors for capacitor switching, can be used in installations in which the peak current far exceeds 100 times nominal rms current
-
The contactors are delivered complete with their damping resistors and must be used without additional inductances (see table below). The capacitors must be discharged (maximum residual voltage at terminals ≤ 50 V) before being re-energized when the contactors are making
-
Their electrical durability is 250 000 operating cycles for Ue < 500 V and 100 000 operating cycles for 500 V ≤ Ue ≤ 690 V
-
The UA..RA contactors are fitted with a special front mounted block, which ensures the serial insertion of 3 damping resistors into the circuit to limit the current peak on energization of the capacitor bank
-
Their connection also ensures capacitor precharging in order to limit the second current peak occurring upon making of the main poles
-
The insertion of resistors allows to damp the highest current peak of the capacitor when switching on, whatever its level
-
The UA..RA series 3-pole contactors are of the block type design
-
