The 300A DC Contactor manufacturer tells you that the DC contactor adopts a modular design, which can assemble the number of contacts required by the customer and the contact form (normally open, normally closed and conversion) required by the customer with the least parts; 300A DC Contactor The manufacturer tells you that this series of products has a high contact breaking voltage and adopts a horizontal blowing magnetic field to extinguish the arc. The maximum breaking voltage can reach 220VDC. The product is suitable for program-controlled power supply or uninterruptible power supply systems, forklifts, electric vehicles, and engineering machinery systems.

Advantages of DC contactor:
1. The manufacturer of 300A DC Contactor tells you that the reliable airtightness allows the product to be used for a long time in harsh and explosion-proof environments. Its internal components such as coils and contacts are not oxidized. At the same time, the product has low energy consumption, low heat generation, long life, and volume. The advantages of small size and light weight.
2. Can control high voltage and high current
3. Energy-saving Some products of specifications use energy-saving panels.
4. The smaller arc makes the product more effective and safer in use. The inert gas is used to seal, so that there is basically no arc between the contacts when the product is in action, and the arc is blown off by magnetic blowing to ensure safety.
5. High stability The internal mechanism and structure are completely sealed in inert gas, free from interference from external undesirable factors, and the contact resistance remains stable for a long time.
6. Wide range of applications, including: DC power supply control, battery switch control, circuit safety protection, etc.
Working principle of DC contactor:
The 300A DC Contactor manufacturer tells you that when the contactor coil is energized, the coil current generates a magnetic field, which makes the static iron core produce electromagnetic attraction to attract the moving iron core and drive the AC contactor
Contact action: The manufacturer of 300A DC Contactor tells you that the normally closed contact is disconnected and the normally open contact is closed. The two are linked. When the coil is de-energized, the electromagnetic attraction disappears, and the armature is released under the action of the release spring.
To restore the contacts: The 300A DC Contactor manufacturer tells you that the normally open contact is disconnected and the normally closed contact is closed.
