A trip latch in a switch housing having an open position and reset-stop position comprising a force member for providing a force to the trip latch. The trip latch also has a primary trip shaft having a first end rotatably connected at opposed first and second ends in the front and rear frame, and a reductor arm extending therefrom. The trip latch further includes a secondary trip shaft rotatably connected at opposed ends to the front and rear frames of the housing proximate and substantially parallel to the primary trip shaft such that the reductor arm engages a bottom portion of the secondary trip shaft. The secondary trip shaft is shaped such that when the secondary trip shaft is rotated the reductor arm may rotate past the secondary trip shaft, thereby causing the trip latch to open.
