The invention discloses a high-current potting terminal post for a breaker, aiming to solve problems such as: difficult to enhance loaded current, vulnerable to wear, short mechanical life, poor contact reliability, etc. The invention comprises a radiator, an upper outlet, an interrupter, a lower outlet, an insulated pull rod, epoxy resin; the upper outlet is mounted with the radiator on the top,and mounted with the interrupter on the bottom; furthermore, the upper outlet also comprises a conducting ring, a soft connection welding component, the upper outlet and the lower outlet are poured by the epoxy resin body; the movable end of the interrupter is connected with the soft connection welding component, the soft connection welding component is connected with the insulated pull rod, the soft connection welding component is connected with the conducting ring, the conducting ring is connected with the lower outlet. By using special conducting jaw welding means, the invention has a plurality of lapping surfaces, with rated loaded current much higher than existing product. The radiating fin is designed in wave shape, in order to enlarge the radiating surface and the contact surface. Also, the invention has excellent insulation performance.
