ABB 1SBL411022R8600 UA75 3-Pole Contactor

Description

• The ABB 1SBL411022R8600 UA75 3-Pole Contactor is a robust and reliable component designed for the specific purpose of switching capacitor banks with inrush current peaks not exceeding 100 times the nominal RMS current. As part of the UA series, this contactor features a block-type design and incorporates three main poles.

• This contactor is ideal for AC control circuits, and its operation is facilitated by a laminated magnet circuit, ensuring high-performance and durability. To assist in the selection of appropriate capacitor banks, a comprehensive table is provided, offering details on permissible powers based on operational voltage and temperature in close proximity to the contactor. The table also specifies the maximum peak current (I_peak) values that the contactor can safely handle under different conditions.

• Safety is a paramount consideration in capacitor switching applications. It is imperative to discharge capacitors to a maximum residual voltage of 50 V before re-energizing when the contactors are in the closed position. Under these conditions, the UA75 contactor is rated for an electrical durability of up to 100,000 operating cycles.

• The UA75 contactor is distinguished by its block-type design, known for its reliability and suitability for demanding applications. Furthermore, it is complemented by a diverse range of accessories, enhancing its versatility and adaptability for various use cases.
