Product Features
- The contact system is installed in the small chamber of the insulating part. The contact system of each phase adopts a multi-path sheet-like structure, realizes electric force compensation and ensures the high breaking capacity of the circuit breaker.
- The advanced arc-extinguishing system and protective cover ensure “zero flying arc”, making the product more secure.
- The circuit breaker is operated for energy storage by the energy-storage mechanism, with a fast closing speed.
- The operating mechanism is installed at the center of the front of the circuit breaker and is completely separated from the main circuit. It can make each phase have a stable and consistent final contact pressure, which plays an important role in ensuring the temperature rise and breaking indicators.
- The centered operating mechanism facilitates symmetric hole-opening in the middle of the complete set of cabinet doors, improving the appearance quality of the complete set of cabinets.
- It can be installed with bottom incoming lines and has horizontal and vertical wiring methods.
- Intelligent controller, with multiple protection functions, can realize selective protection.

Frequently Asked Questions
Q: What is the operating temperature range for the ATA3200 circuit breaker?
The ambient air temperature for normal operation must be between a lower limit of -5°C and an upper limit of +55°C.
Q: What is the maximum installation altitude without derating?
The standard installation altitude should not exceed 2000 meters. For higher altitudes, a high-altitude derating coefficient must be applied.
Q: What protection classes are available for installation?
The device meets IP30 and IP40 protection requirements when installed in the cabinet compartment with door frames and organic glass covers added.
Q: Does the ATA3200 support vertical wiring?
Yes, the circuit breaker supports both horizontal and vertical wiring methods, and can be installed with bottom incoming lines.
Q: What is the mechanical life expectancy of this circuit breaker?
The mechanical life is 10,000 operations under maintenance-free conditions, and can reach up to 20,000 operations when required maintenance is performed.
Q: What safety benefits does the arc-extinguishing system offer?
The advanced arc-extinguishing system and protective cover ensure "zero flying arc", which makes the product and the operating environment significantly more secure.
