GCS-Type ATS Power Cabinet
Internal Components
Core Transfer Components: Equipped with the Chint NH40 series ATS dual-power transfer switch, which supports a large current of 2500A and features both automatic and manual switching modes. As the core component for fast switching between main and standby power supplies, it ensures precise and stable switching logic.

Monitoring and Protection Components: Built-in current transformers can detect circuit current data in real time, providing a reliable basis for switching decisions. Equipped with circuit breakers and fuses, it can quickly respond to circuit faults such as overload and short circuit to prevent the expansion of faults.

Control and Wiring Components: Integrated with a control panel with a display screen and operation buttons, it supports real-time monitoring of power parameters and manual adjustment of modes. Standardized terminal blocks and wiring modules are adopted to standardize the wiring process and improve the operational stability and maintenance convenience of the cabinet.

Product Advantages
High Reliability and Compatibility: Selected well-known brand components such as Chint, it is suitable for 2500A industrial-grade high-current loads to meet the needs of high-power electricity consumption scenarios. The cabinet is designedin accordance with the GCS cabinet type standard, which can be flexibly connected with various power distribution systems and has strong compatibility.

Automation and Emergency Support: It operates in automatic mode by default, and can switch to the standby power supply within ≤ 100ms when the main power supply fails, greatly reducing manual intervention and power outage losses. The manual emergency operation function is retained to balance the efficiency of automation and power supply guarantee in extreme scenarios.

Safety and Easy Maintenance: It has dual protection functions of overload and short circuit, and is designed with IP55 protection level to effectively isolate dust and water vapor intrusion. Standardized wiring and modular structure make daily inspection, component replacement and other maintenance work more efficient.

Application Scenarios
Industrial Production Scenarios: Suitable for various industrial plants and manufacturing workshops, it provides continuous and stable power supply for production line equipment and heavy machinery, avoiding production interruption and equipment damage caused by power outages.

Commercial and Public Building Scenarios: Applicable to commercial buildings such as shopping malls, office buildings and hotels, as well as transportation hubs such as airports and high-speed railway stations, it ensures the uninterrupted operation of key facilities such as lighting systems, elevators and central air conditioners.

High-demand Special Scenarios: For data centers and communication base stations, it can prevent data loss of servers and communication equipment due to power outages. It is suitable for medical places such as hospital operating rooms and intensive care units to provide reliable power support for life support equipment.
Frame circuit breaker
Frame circuit breaker, also known as frame type circuit breaker, is an important electrical equipment used for circuit protection. A frame circuit breaker is an electrical device that can quickly cut off the circuit when detecting faults such as overcurrent, overload, and short circuit. Its main function is to protect electrical equipment and circuits from damage, effectively preventing fires and other safety issues caused by faults.

Multiple protection functions: The frame circuit breaker distribution cabinet has multiple protection functions such as overload, short circuit, undervoltage, and ground fault, which can achieve selective protection, avoid unnecessary power outages, and improve power supply reliability.

Flexible installation and connection methods: Supports fixed and drawer installation, can adapt to different space and usage requirements. At the same time, multiple connection methods such as horizontal and vertical wiring are provided, making it convenient for users to choose according to their actual wiring needs.

Intelligent and communication functions: Some framework circuit breaker distribution cabinets are equipped with intelligent release devices, which have measurement and display functions for parameters such as current and voltage, and can also achieve remote monitoring and communication, making it easy for users to grasp the real-time operation status of the equipment.
