The so-called dual circuit transfer switch is a switch that can be used to switch between two circuits. One switch controls a group of batteries. When the first group of batteries runs out of power, push the second group of battery switches, and the switch controlled by the first group will automatically fall. The two switches cannot be turned on at the same time.Dual conversion electric motorcycle circuit breakerIt is an addition of overload and short circuit protection functions on the basis of dual circuit transfer switches, which can be directly used for electric vehicle circuit switching and protection.
1. When the left switch of the dedicated circuit breaker for dual circuit electric vehicles is turned on, the right switch automatically drops and the battery ① starts working.
2. When the dedicated circuit breaker for dual circuit electric vehicles is opened on the right side, the left switch is manually lowered, and battery ② starts working.
3. When in use, the two control switches cannot be turned on at the same time. When one switch is pushed on, the other automatically drops, providing a safety protection circuit to prevent overload.

1. Improved the seismic performance of the circuit breaker, ensuring no power outage due to misoperation.
2. Increasing contact pressure, reducing contact resistance, effectively reducing the internal resistance of the circuit, thereby improving the volt ampere characteristics of the electrical system.
3. The use of special magnetic materials can reliably extinguish fault arcs, ensure the only direction of current flow, form magnetic blowing arcs, and ensure the safe operation of the system.

Most of the air switches that come standard with electric vehicles on the market now are AC type, and AC air switches pose significant risks in DC circuits! It is particularly necessary to equip your electric vehicle with a genuine DC circuit breaker!
Every cycle of alternating current has a natural zero crossing point, which makes it easy to extinguish the arc; And direct current has no zero point, making it difficult to extinguish an arc. It is easy to extinguish arcs in AC systems, but more difficult to extinguish arcs in DC systems. Due to different systems and arc extinguishing principles, there are significant differences in structure and performance between AC circuit breakers and DC circuit breakers. Compared to AC circuit breakers,Electric vehicle circuit breakerAdditional arc extinguishing devices need to be added to enhance the arc extinguishing capability. In principle, AC circuit breakers should not be used in DC circuits.
The electric motorcycle circuit breaker DZ47SD-B63 has the current limiting performance of a small circuit breaker, which can accurately protect relay protection and automatic devices from overload, short circuit and other fault hazards. The advantages of current limiting and arc extinguishing capabilities possessed by electric motorcycle circuit breakers, after extensive comprehensive scientific experiments, can achieve fully selective protection between the main (sub) screen, protection screen, and relay screen levels in DC systems.
DC bipolarElectric vehicle air switchBy using a special arc extinguishing and current limiting system, the fault current of the DC distribution system can be quickly cut off, greatly improving the level difference coordination. Small DC circuit breakers are particularly designed for accidents such as over class tripping between the measurement and protection screen and the distribution screen in power engineering DC systems. This series of small DC circuit breakers has excellent performance and can avoid the above-mentioned faults. The differential matching characteristics of small DC circuit breaker products are the best among similar products at home and abroad.
This DC bipolar electric motorcycle circuit breaker has been tested by our company and is designed specifically for various high-power DC powered vehicles such as electric motorcycles, electric tricycles, and electric quadricycles. According to the power demand, the continuous load capacity of this circuit breaker is divided into nine products: 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, and 63A.
