LW35 serial circuit breakers, including LW35-72.5, LW35-126, LW35-145 and LW35-252 products, are designed with self-energizing principle that arc generated in the interrupter is distinguished at a specified time with a part of energy produced by the arc itself. They are used for making and breaking normal current, fault current and switching lines to realize the operation (three-pole opening & closing operation and fast automatic-reclosing operation), control and protection of power system.
