The invention relates to an integrated energy trip device with pre-trip function, wherein said device comprises: a rotation arm, a piston and an air channel; two ends of air channel have air holes near them; the activate end of rotation arm protrudes out the frame; and it comprises one insert rod at one side of rotation arm; the insert rod and the frame form movable couple; the insert rod has concave cut; the rotation arm extends to the reverse end; when the insert rod is at the middle position, the reverse end contacts the insert rod and the activate end is at the trip position; when the insert rod is inserted, the reverse end is fallen into the concave cut of insert rod and the activate end is movable. With said invention, the trip device and the pre-trip device are combined, to confirm the former function of energy trip device, and confirm the breaker state. |
