| 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: How is the DC contactor connected to the circuit
- the contactor is divided into two parts is a coil through the control switch and power in parallel, the other is the contact switch and load in series
- Q: Various types of contactors are classified
- This non-contact power electronic switch circuit does not produce arc, which avoids the traditional contactor arc on the contact material of electrical wear, it greatly increases the contact life and reliability
- Q: What is the use of AC contactors?
- The power is applied and the contact point is disconnected after power failure
- Q: What is the number of AC contactors?
- AC contactor series is the number of phases, there are two-phase, three-phase, four-phase and so on
- Q: The contactor is mainly composed
- 20 amperes above the contactor with an arc extinguishing cover, the use of electromagnetic circuit generated when the circuit off, quickly pull off the arc, protect the contacts
- Q: With long life, long reliability is the advantages of traditional communication contactor
- When the opening, the permanent magnet AC contactor in addition to the role of sub-gate spring
- Q: What is the difference between the auxiliary system 01 and 10 of the AC contactor?
- The so-called normally open contact is the contactor coil without electricity in the case of moving, static contact is separate, non-conductive, generally used NO said, normal open
- Q: What is the contactor's formula?
- The rated current and rated voltage of the low voltage circuit breaker shall not be less than the normal operating voltage of the line and the calculated load current (the total current at all load operation, multiplied by the actual situation)
- Q: What is the main component of the contactor?
- one of which is fixed with a coil and a working voltage. select. In order to stabilize the magnetic force, the suction surface of the core is short-circuited. The AC contactor relies on a spring return after power failure.
- Q: What causes the AC contactor to be damaged
- Damage to the product itself (such as the coil broken or burned, the mechanical moving part was stuck, the shaft rust or skew, etc.) 5. Contact spring pressure and overtravel. Increase the supply voltage
