A. We offer one year warranty for our products. Please feel assured.

Q 6.Do you accept OEM business ? 

We accept OEM authorization.



Q:Three-phase AC contactors have several useful clients?
Also note that the voltage applied to the power supply is much (220V or 380V), are generally marked.
Q:What is the difference between a contactor and a circuit breaker?
Depending on the specific brand, model may be. Its sub-closing can be manually or electrically
Q:Contactor dynamic performance detection technology and comprehensive evaluation method
and can not be on the dynamic characteristics of electrical appliances and mechanical life of the impact of comprehensive assessment.
Q:Why should the thermal relay be used with the AC contactor
triggering the normally closed contact of the thermal relay to disconnect the AC contactor coil circuit, and the AC contactor After the coil is lost, the main contact is reset and the motor is stopped
Q:Whether can the AC contactor cut off the short circuit current?
When the coil is powered off, the suction disappears, and the moving core interlocking part is separated by the reaction force of the spring
Q:Computer-centric development trend
The device can realize real-time data acquisition of dynamic waveforms such as contact voltage and current for contactor and breaking process.
Q:What is the traditional AC contactor contact that does not vibrate?
When the voltage fluctuates in the critical state of closing and opening, the contactor is in the same way, Vibration, resulting in contact welding or burned, leaving the motor burned.
Q:Seeking Star Triangle to start the contactor on and off the order and process
when the press button SB1, the time relay coil KT and then contact the coil at the same time Power, KMY's moving contact closed
Q:What about the number of AC contactors?
When the coil is powered off, the suction disappears, and the moving core interlocking part is separated by the reaction force of the spring
Q:Permanent magnet AC contactor working principle
Permanent magnet AC contactor is the use of the magnetic pole of the same-sex repulsion, the opposite sex suction principle,
