High Voltage DC Contactor Coil Schematic
Tips: Reasons for the contacts of contactor being unable to close after powering on
- Power supply circuit of the coil shorts.
- Coil circuit breaks.
- Coil's control voltage is too low.
- The contactor's coil has burnt out, thermal deformation of coil skeleton makes the iron core
- unable to be sucked to a proper place, thus the contact can't close.
- Adhesion of main contact.
- A foreign body or hard spots in the armature.
- Main contact dislocates (mainly for large contactor, bridge type contact).
- Auxiliary contact is not well installed.
Cheap Price DC contactor relay, normally open (SPST-NO) type , 30 amps rated load current of contact circuit, available with 12V or 24V coils. Magnetic contactor is widely used in the DC 12-900V high voltage field, offers exceptional performance in an extremely small and lightweight device.
