Product Description

  • UA50..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. - Main poles: 3 main poles Control circuit: AC operated with laminated magnet circuit
