63A Solar Panel Load Auto Changeover Switch ATS
The RDQ3NX-A/B/C/D series 63A Solar Panel Load Auto Changeover Switch ATS by Radin Electric Technology Co., Ltd. is a modular dual-power transfer device introduced in 2009 to address limitations of MCB-type ATS units, including insufficient functionality and reliability. This series holds three patents (invention, utility model, and appearance) and integrates two MCB circuit breakers with a mechanical interlock system and intelligent controller. The A, B, C, and D control configurations offer progressive features: A provides auto changeover, auto recovery, and phase-missing protection; B adds generator start, fire linkage, and time delay; C and D include three-phase voltage monitoring.
Constructed with a gear-driven mechanical transmission to prevent simultaneous closing, the RDQ3NX series maintains overload and short-circuit protection inherent to the breakers. Its compact design is among the smallest in the market, with a working power voltage range of AC200-400V and a peak power loss of 4.8W, roughly 20% of comparable products. The modular design allows independent replacement of executive units, transmission mechanisms, and control circuits, while single-chip control separates working and sampling power to mitigate electromagnetic interference. Typical for solar ATS applications, the unit supports seamless switching for critical loads in off-grid or hybrid systems.
This ATS is used in solar power installations, backup generator systems, and industrial facilities requiring uninterrupted power for sensitive equipment. Buyers include solar farm operators, commercial building managers, and OEMs integrating power reliability solutions. The series supports various executive circuit breakers and is designed for easy installation and component interchangeability. Originating from Yueqing, Zhejiang, the product is shipped globally, with delivery terms negotiable based on order volume and destination.

Sourcing 63A Solar Panel Load Auto Changeover Switch ATS from Radin Electric Technology Co., Ltd. - China Import Guide
Before ordering, verify the compatibility of the RDQ3NX series with your specific power sources, including voltage, frequency, and phase requirements. Confirm that the ATS model supports your intended control configuration (A, B, C, or D) and that its protection functions align with your system’s needs. Request the supplier’s test reports or certifications to ensure compliance with IEC 60947-6-1 or other relevant standards for your region.
Logistics details should be clarified upfront, as the supplier’s delivery terms include shipment, express, and air express options. Confirm lead times, which may vary based on order volume and customization requirements. Incoterms such as FOB, CIF, or EXW should be agreed upon, along with payment terms (e.g., TT, LC) to avoid delays. Yueqing’s proximity to major ports like Ningbo or Shanghai can facilitate efficient shipping for international buyers.
Quality checks should include testing the mechanical interlock system to ensure it prevents simultaneous closing and validating the transfer time under load. Inspect the ATS for proper modular assembly and verify that all protection functions (overload, short circuit, phase missing) are operational. Request documentation such as patents, test certificates, and compliance declarations to confirm the unit’s reliability and adherence to industry standards.
