The invention discloses a high-current relay capable of adjusting over-travel. The relay comprises a coil frame, a moving spring armature component and a base. A flange on one end of the coil frame isprovided with a first hook component downward. A first clamp hole is arranged at a corresponding position of the base. The first hook component of the coil frame fits into the first clamp hole of thebase. A flange on the other end of the coil frame is provided with a second hook component downward. A second clamp hole is arranged at a corresponding position of the base. The second hook componentof the coil frame fits into the second clamp hole of the base. According to the invention, on one hand, disadvantages caused by rivet splitting and fixing in the prior art are avoided on the basis ofstable fixation between a magnetic circuit part and the base; and on the other hand, over-travel adjustment of the high-current relay is realized.
