Information

The 300A DC Contactor manufacturer tells you that the main circuit current of the DC contactor is DC, which is usually rarely used. Mainly used for DC motor control of precision machine tools. 300A DC Contactor manufacturers tell you that the contactor adopts a modular design, which allows the customer to assemble the number of contacts and the form of contacts required by the customer with a minimum of parts.

good price and quality 300A DC Contactor company
The 300A DC Contactor manufacturer tells you that the DC contactor product has a high contact breaking voltage and uses a horizontal purging magnetic field to extinguish the arc. The maximum cut-off voltage can reach 220VDC. Applicable to frequency converter, telecommunication power supply, battery car, traction locomotive and uninterruptible power supply system.
How to choose a DC contactor:
1. Select the type of DC contactor
300A DC Contactor manufacturers tell you that the type of DC contactor should be selected according to the type of load current and the weight of the load, that is, AC load or DC load, light load, normal load or heavy load.
2. The rated current of the main contact of the DC contactor
The rated current of the main contact of the DC contactor can be calculated according to the empirical formula. IN main contact PN motor/(1~1.4)UN motor. 300A DC Contactor manufacturers tell you that when the motor controlled by the DC contactor frequently starts, brakes or reverses, the contactor is usually the main contactor, and the rated current of the contact is reduced by one level.
3. The 300A DC Contactor manufacturer tells you that the voltage indicated on the nameplate of the main contact rated voltage contactor refers to the rated voltage that the main contact can withstand, not the voltage of the pull-in coil. When in use, the rated voltage of the main contact of the contactor shall not be lower than the rated voltage of the load.
4. Select the operating frequency
The operating frequency refers to the number of times the contactor is switched on and off per hour. If the on-off current is large and the on-off frequency is too high, the contacts will be seriously overheated or even blown. 300A DC Contactor manufacturers tell you that if the operating frequency exceeds the specified value, a DC contactor with a rated current of class 1 must be used.
