4P (4NO) AC contactor

4P (2NO+2NC) AC contacor

Tips: Basic principle of 4 Pole contactor
When the coil is energized, the static iron core generates electromagnetic attraction, and the moving iron core is sucked. Since the contact system is linked with the moving iron core, the moving iron core drives the three movable contact pieces to operate at the same time, and the contacts are closed, thereby being connected. power supply. When the coil is de-energized, the suction force disappears, and the moving core interlocking portion is separated by the reaction force of the spring, so that the main contact is disconnected and the power is cut off.
Lowest price AC contactor on sale, 4 pole, 24 volt, 110 volt and 220 volt coil can be selected, it is avaliable with contact form 4P (4NO) or 4P (2NO+2NC). When bypass contactor used in AC-3 380V, the rated current is 40A, when used in AC-3 660V, rated current is 34A, favorable price and high safety.
