3. The 600A DC Contactor manufacturer tells you that the iron core of the AC contactor will produce eddy current and hysteresis loss, and the 600A DC Contactor manufacturer tells you that the DC contactor has no iron core loss. Therefore, the iron core of the AC contactor is made of laminated silicon steel sheets that are insulated from each other, and is often made into an E shape; the iron core of the DC contactor is made of a whole piece of mild steel, and most of them are made into a U shape.
4. The manufacturer of 600A DC Contactor tells you that because the AC contactor passes single-phase alternating current, the manufacturer of 600A DC Contactor tells you that in order to eliminate the vibration and noise generated by the electromagnet, a short-circuit ring is embedded on the end of the static iron core, and the DC contactor No need.
