ABB 1SBL351022R8811 Contactor

Description

• The ABB 1SBL351022R8811 UA50 3-pole contactors are designed for efficient and reliable switching of capacitor banks. These contactors are suitable for applications where the inrush current peaks of the capacitor banks are less than or equal to 100 times the nominal rms current. They provide dependable performance for such applications.

• A critical safety consideration when using these contactors is to ensure that the capacitors are discharged, resulting in a maximum residual voltage at terminals of less than or equal to 50 V before re-energizing when the contactors are in the making position. This safety measure is essential for safe and reliable operation.
