The contactors are supplied complete with their damping resistors and must be used without additional inductors. Their electrical lifespan is 250,000 switching operations at Ue < 500 V and 100,000 switching operations at 500 V = Ue = 690 V. The UA..RA contactors are equipped with a special front block that ensures the serial insertion of three damping resistors into the circuit, to limit the current peak when energizing the capacitor bank. Their connection also ensures the pre-charging of the capacitors to limit the second current peak when the main poles are switched on. By using resistors, the capacitor's highest current peak can be attenuated when switched on, regardless of its magnitude. The 3-pole contactors of the UA...RA series are designed in a block design. - Main poles: 3 main poles - Control circuit: AC operated with laminated magnetic circuit
