Scope of Application
As a designated CB-level (C) device, the ZYQ1 series possesses integrated protective functions, acting simultaneously as a high-speed transfer switch and a circuit breaker. It is capable of defending the system against short circuits, overloads, undervoltage, and total loss of voltage. Its architectural focus on 3-pole (3P) and 4-pole (4P) configurations makes it the definitive choice for lighting and power circuits in high-rise buildings, shopping malls, banks, hospitals, and transit stations that require specialized fire protection and reliable status signaling. The series is fully compliant with the GB/T 14048.11 standard, ensuring it meets the most rigorous safety benchmarks for modern commercial and industrial facilities.
Application Scenarios
Normal working conditions
The device is built to manage diverse humidity profiles. At a peak temperature of +40°C, the relative humidity must remain below 50%. In cooler conditions, such as +20°C, humidity up to 90% is permissible, provided that the housing is protected against condensation caused by rapid temperature fluctuations. Classified under Pollution Degree 3, the ZYQ1 is resilient against conductive dust and non-corrosive vapors, making it suitable for industrial environments free from intense vibration, explosive hazards, or strong electromagnetic interference.
Structural features
The structural excellence of this series is reflected in its clear and logical Type & Meaning architecture, which allows for precise customization during the procurement process. The naming convention flows from the Enterprise Code Name and Basic Type (Q) to the Design Serial Number (1). The Shell Frame Level Current Rating (63) indicates its robust physical capacity, while the model selection allows for a choice between the Miniature type (R) and the New type (L). Furthermore, the ZYQ1 supports four distinct Wiring types (A, B, C, or D), offering engineers the flexibility to match the internal logic and terminal arrangement to the specific wiring architecture of the project.
Mechanically, the switch utilizes a Single-Machine Drive System, which ensures a stable, noiseless transition with minimal impact force, significantly extending the service life of the internal components. For operator safety, the ZYQ1 features a Dual-Safety Interlocking System, which integrates a physical mechanical interlock with electronic logic to strictly prevent the simultaneous closure of primary and standby sources. The front panel is equipped with a digital visualization module, LED indicators, and a manual/automatic mode selector, providing real-time feedback and emergency manual control capabilities.
Product Model and Its Meaning
Technical Parameters
Integrated CB-Level Dual Power Protection: The "C" designation in the model name identifies its nature as a CB-level ATS. This means the device contains built-in thermal-magnetic trip units that provide comprehensive overcurrent and short-circuit protection. The Circuit breaker rated current (A) can be specified to match the exact load requirements, separate from the 63A shell frame level.
Rapid Switching Performance: Time-sensitive terminal loads rely on the ZYQ1’s optimized transfer logic. The switch typically achieves a high-speed transfer speed (TSE) of under 100ms, minimizing the "off-time" and ensuring that lighting systems, security surveillance, and basic medical monitors do not experience catastrophic resets during a power failure.
Fire Safety & Signal Feedback: A critical feature of the ZYQ1 is its fire protection linkage. The switch includes a dedicated interface that allows it to be forced into the "Zero" (Double-break) position upon receiving a fire control signal, effectively isolating the affected area. Additionally, the integrated terminal blocks reflect the real-time status (Open/Closed) of the circuit breakers for integration into SCADA or BMS networks.
Configurable Pole and Wiring Options: By focusing exclusively on 3 pole and 4 pole configurations, the ZYQ1 ensures perfect compatibility with balanced and unbalanced three-phase systems. The choice of Wiring type (A, B, C, or D) further allows for seamless integration into diverse panel board layouts and grounding schemes.
Standards and Durability: The ZYQ1 series is engineered for a high rated insulation voltage (Ui) and an impulse withstand voltage (Uimp) of 8kV. With a mechanical durability rated for thousands of cycles and full compliance with the GB/T 14048.11 and IEC 60947-6-1 standards, it represents a safe and future-proof investment for modern smart building infrastructure.
