Function

The arc chute is a vital component of a contactor’s arc extinguishing system. When the contactor’s main contacts open under load, a high-temperature, high-energy electrical arc is generated. The arc chute, made from insulating and arc-resistant materials, channels this arc into a series of metal plates (arc splitters). These plates cool, lengthen, and divide the arc into smaller, weaker segments, which are then quickly extinguished. The 3RT1966-7A performs this crucial function for the 3RT1056, ensuring a clean and safe interruption of the electrical current.
