Circuits Diagram

Tips: Characteristics of DC contactor
- DC contactor’s iron core and armature are made of a single piece of solid material instead of silicon steel sheet.
- The DC voltage coil has a large DC resistance value.
- It has DC main contacts and auxiliary contacts of varying numbers. Some main contacts are equipped with arc extinguishing devices, and some do not have arc extinguishing devices. The DC contactor is mainly used to connect and disconnect the load in the DC circuit remotely.
3 or 4 pole AC contactor is an electrical switching device to control electric motors, lighting and other electrical loads at 40 amp rated current. Rated power up to 30 kW, contact form 3 NO or 2NO+2NC, coil rated voltage of 12V, 24V, 36V, 48V, 110V, 220V for your choices.
