Product Description:

Application
AC contactor(hereafter refer to ac contactor)is mainly used in power system with AC 50Hz(or 60Hz), the rated working voltage up to 660V, under the application category of AC-3, when the rated working voltage 380V, the rated operating current to 300A electrical, for the long-distance range making and breaking the electric circuit, and combines the electormagnetism starter with the suitable thermal overload relay or the electronic protector to protect against the possible overload electric circuit during operation(running).

Q:Determine whether the AC contactor can cut off the short circuit current?
Since the contact system is linked with the moving core, the movable iron core drives the three action contacts at the same time, the main contact closes, and the main Contact mechanical connection of the auxiliary normally closed contact open
Q:What is the main component of the contactor?
AC contactor contacts, made of silver tungsten alloy, with good conductivity and high temperature ablation
Q:The contactor is mainly composed
The service life of the contactor is very high, the mechanical life is usually several million to ten million times, and the electrical life is generally several hundred thousand to several million times.
Q:Contactor accessories have what roles?
arc extinguishing device, the general capacity of the larger AC contactor are equipped with arc extinguishing device, in order to quickly cut off the arc, from burning the main contact;
Q:How to get the relay time parameter
The literature refers to a relay time parameter computer detection method, which uses self-developed acquisition board, which is mainly composed of single-chip and its peripheral circuit
Q:How to connect the DC contactor to the circuit?
Why use it? Because 1, some switches are not only used a switch, such as the motor star - angle start once there are several switches at the same time action
Q:Contactor mainly by the drive system, contact system, arc and other components.
drive system: the drive system, including electronic modules, soft iron, permanent magnet, is an important part of permanent magnet contactor, relying on it to drive the contact closure and disconnect
Q:Can the AC contactor cut off the short circuit current?
Because the AC contactor is only a switch-type device, no current detection and feedback device, so in practice, often with the appropriate thermal relay or electronic protection device into an electromagnetic starter, in order to protect the circuit may occur overload or phase failure.
Q:Contactor dynamic performance detection technology and comprehensive evaluation method
. In this paper, the dynamic response of the contactor is tested, and the parameters of the contactor mechanical and electrical characteristics are extracted from the contact test waveform
Q:Basic classification of AC contactors
The contactor is mainly composed of electromagnetic system, contact system, arc extinguishing system and other parts.
