30A High Voltage DC Contactor Features

DC 12-900V rated load voltage of contact circuit.
SPST-NO of contact form, 12 volt, 24 volt coil for selecting.
Main contact voltage drop at 30A, not above 100mV.
The connection of contact and coil need to be nonpolarity.
Efficient coil, retentive power is only 2-2.3W, counter electromotive force is 0V.
The joint way of the coil is very convenient.
The coil has no counter force of electromagnetism.
Compare to the similar products, this product is smallest and lightest.

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.
