Removable contact system, characterized by removing easy, easy install. Avoid contact under high current state driven by electromagnetic forceTurns and added a pair of holes on both the contacts, enhance convection, lower temperature rise.
Detachable contact system, which is easy to disassemble and easy to install. To avoid contact in the high current state by the electric power driven by the rotation of the contact block at the same time on the increase of a pair of holes, to strengthen the convection, lower temperature rise.
