ABB 1SBL411025R8100 Single-Pole Contactor

Description

• The ABB 1SBL411025R8100 GA75 contactors are specifically designed for DC circuit switching, where arc suppression can be more challenging compared to AC circuits. When selecting a contactor, it is essential to have information about the current and voltage that need to be interrupted, as well as the L/R time constant of the power circuit to be controlled.

• These GA75 contactors feature a block-type design and come equipped with specialized features for efficient DC breaking. The main poles of these contactors are fitted with arc chutes that incorporate permanent magnets, which are specially designed for DC breaking. The three contactor paths are arranged in series via two supplied and fitted insulated connections (25 mm²).

• The GA75 contactors are "single-pole" devices, and it's crucial to respect the connection polarities indicated next to the connection terminals. They are marked as 1L1 for the positive terminal and 2T1 for the negative terminal.
