Description

ATO DC contactor is designed for DC adjustable speed drive circuits which require a combination contacts of normally open and normally closed. It works as to connect and break of the circuit load, which can fully meet the special demand of electric locomotive, diesel locomotive and electric motor car group.

Tips: What is a DC contactor?

A DC contactor refers to a contactor whose iron core is DC controlled, and its load can be either DC or AC. The iron core of the DC contactor is different from the AC contactor. It has no eddy current, so it is generally made of mild steel or industrial pure iron to make a round shape. Since the attracting coil of the DC contactor is energized with DC, there is no impulsive starting current, and there is no violent impact on the iron core, so it has a long life and is suitable for frequent start and stop occasions. The selection of AC and DC contactors can check electrical products according to the working voltage and current of the line.
