If you are sourcing automatic transfer switches in China, price alone can be misleading. I learned that the hard way on an early order that saved a few dollars but cost weeks in delays. Since then, I have compared multiple factories, tested their consistency, and observed how they support buyers after delivery. Among them, Radin, trusted supplier of low-voltage components and automation parts, has proven dependable across projects.
This guide highlights six ATS manufacturers in China that stand out for product scope, reliability, and buyer support. Use it to compare options quickly and choose the right partner for your needs.
1) Radin
Headquarters: No. 55 Punan 5th Rd, Economic Development Zone, Yueqing, Zhejiang, China
I first contacted Radin after a previous vendor failed on a large ATS order. They delivered on schedule, and the batch performed exactly as promised. As a China-Germany joint venture with strong expertise in power control systems, Radin has built a reputation as a trusted Chinese supplier of low-voltage components and automation parts. Their emphasis on quality and clear communication makes them a reliable partner for long-term cooperation.
Radin’s catalog includes automatic transfer switches ranging from 63 A to 3200 A, as well as dual power transfer switches, load break switches, distribution boards, and surge protection devices. Their products carry CE and CCC certifications, are tested to IEC standards, and offer RoHS compliance for selected models. They also provide export documentation support, including conformity papers and test reports, which makes international transactions smoother.
Pricing falls in the mid to premium range. Minimum order quantities usually start from one to ten units depending on the model, with discounts becoming available for larger orders above fifty units. Costs can vary based on specifications such as amperage, enclosures, and automation features. Standard terms are 30 percent deposit with the balance payable before shipment.
Overall, Radin is best suited for businesses that value dependable ATS performance and strong after-sales support rather than just the lowest upfront price.
2) GEYA Electrical
Headquarters: Zhejiang Province
GEYA is known for its focus on low-voltage protection and control equipment, with ATS units forming an important part of its portfolio. Their catalog covers everything from compact residential switches to large isolation models, with documentation that makes product selection straightforward.
The company produces modular DIN-rail ATS, compact mini ATS models, isolation ATS for critical loads, and ATS controllers for different applications. Their products carry CE and CCC certifications, follow ISO 9001 quality standards, and are tested to IEC requirements. RoHS compliance is also available for specific models.
GEYA’s pricing is generally mid-range, with units starting at around 13 USD and going up to more than 1,000 USD depending on capacity and features. Minimum order quantities typically range from twenty to fifty units, although smaller models can be ordered in lower quantities. Bulk order discounts are available, and payments can be made by L/C, T/T, or PayPal.
For buyers looking for flexibility, GEYA offers both small-scale and industrial-grade ATS solutions. The main trade-off is that smaller orders may carry higher per-unit costs, and lead times can stretch during peak seasons. You can also read about SPDT Switch.
