ABB 1SBL371022R5500 UA63 3-Pole Capacitor Switching Contactor

Description

• The ABB 1SBL371022R5500 UA63 contactor is specifically designed for the switching of capacitor banks. It is suitable for applications where the inrush current peaks of the capacitor banks are less than or equal to 100 times the nominal RMS (Root Mean Square) current.

• This contactor is well-suited for controlling capacitor banks used in various electrical systems. It is essential to ensure that the capacitor banks are discharged, with a maximum residual voltage at the terminals not exceeding 50 V, before they are re-energized while the contactor is in the closed (making) position. Under these conditions, the electrical durability of the contactor is rated at 100,000 operating cycles, ensuring reliable and long-lasting performance in capacitor switching applications.

• The UA63 contactor belongs to the UA... series and features a 3-pole configuration. It is designed in a block-type format, making it suitable for a wide range of capacitor switching scenarios.
