Although PC-level switching performance is excellent, the price is high, which is a considerable waste for non-core loads; and in the event of a power outage, business and life will come to a standstill with single-power supply. The ATS Dual Power Automatic Transfer Switch-CB from Junray Electrical abandons the expensive isolation switch structure and adopts a mature and economical circuit breaker combination solution. This means that you don't have to pay a high premium to obtain reliable dual-power automatic switching functionality. It perfectly balances cost and performance, allowing ordinary users to afford the "no-power-loss" guarantee and completely resolves the contradiction between limited budget and the need for power supply.
The core competitiveness of the ATS Dual Power Automatic Transfer Switch-CB lies in its unique "circuit breaker + controller" structural design:
High cost-effectiveness: Compared to PC-level products, the CB-level solution uses standardized plastic-encased circuit breakers as the actuator, significantly reducing manufacturing costs. For ordinary loads that do not require millisecond-level switching (such as lighting, sockets, and ordinary power), this is the most cost-effective choice.
Dual protection functions: This is a major highlight that distinguishes it from PC-level. Since the circuit breaker is used as the main switch, it comes with overload and short-circuit protection functions. Whether it's the main power supply or the backup power supply, once an abnormal current occurs in the line, the circuit breaker will automatically trip to cut off the fault, preventing line burnout and equipment damage, equivalent to giving both power sources a "bulletproof suit".
Automatic seamless monitoring: With an internal intelligent controller, it monitors the mains voltage in real time. When the mains power is off, phase missing, or the voltage is abnormal, it can automatically start the switching mechanism to transfer the load to the backup power supply, ensuring uninterrupted power supply. Although the switching time is slightly longer than that of PC-level, it fully meets the needs of most civilian and commercial scenarios.
As a professional Manufacturer with profound technical expertise, Junray Electrical strictly adheres to the national standards for CB-level dual power automatic transfer switches in its production. Our factory is equipped with a mature circuit breaker assembly line and an intelligent controller testing platform, ensuring that each product is sturdy and durable.
This ATS Dual Power Automatic Transfer Switch-CB features reliable mechanical and electrical interlocks for dual protection, preventing short circuits caused by simultaneous connection of the two power sources. Each switch undergoes strict power-on debugging, switching logic testing, and protection characteristic testing before leaving the factory, ensuring stable operation within a wide current range of 32A to 800A, and providing you with a reliable power switching service for a long time.

Q: What is the main difference between CB-level and PC-level dual power supplies?
A: The main difference lies in the protection functions and price. CB-level (like this product) consists of circuit breakers and comes with overload and short-circuit protection. It is cheaper and suitable for general loads; PC-level is composed of disconnectors and does not have short-circuit protection capability (requires an external fuse); it has a faster switching speed and is more expensive, suitable for core loads. For most ordinary scenarios, CB-level is the most cost-effective choice.
Q: Can this switch be installed in an ordinary distribution cabinet?
A: The ATS Dual Power Automatic Transfer Switch-CB adopts a standardized structural design, with a compact size and low space occupation. It can be easily installed in standard distribution boxes or control cabinets, and the installation method is similar to that of a regular circuit breaker, which is very convenient.
Q: Is custom current and pole count supported?
A: Yes. We can customize current levels ranging from 32A to 800A according to your project requirements, as well as pole configurations of 3P or 4P, to perfectly meet your dual power switching needs.
