Working Principle When the coil is energized, the electromagnetic force attracts the armature to close, driving the moving contacts to connect with the static contacts, thus turning on the main circuit. When the coil is de-energized, the electromagnetic force disappears, and the armature resets under the action of the return spring, separating the contacts and disconnecting the circuit. The arc generated during contact switching is quickly extinguished through the arc extinguishing chamber to protect the contacts.

Installation Requirements

• Install on a flat surface with standard 35mm DIN rail or fixed screws
• Keep the contactor in a vertical position with the terminal side facing down as recommended
• Select cables with appropriate cross-sectional area according to the rated current
• Tighten the terminal screws to the specified torque to avoid overheating
• Reserve enough space around for heat dissipation and maintenance

Usage Precautions

• Do not use the contactor beyond its rated voltage and current specifications
• Regularly check the contact wear and replace the contact module when the wear limit is reached
• When used in inductive load circuits, it is recommended to install surge suppression accessories
• Do not open the arc extinguishing chamber when the circuit is energized
• The coil voltage must match the control power supply to avoid coil burnout
