Normal Operating and Installation Conditions
Ambient Air Temperature
The upper limit shall not exceed +55°C, and the lower limit shall not be less than -5°C.
Altitude Limit
The altitude of the installation site shall not exceed 2000m. The high-altitude derating coefficient can be referred to.
Atmospheric Conditions
At +55°C, relative humidity shall not exceed 50%. Higher humidity is allowed at lower temperatures (e.g., 90% at +20°C). Condensation measures required.
Pollution Degree
Level 3 pollution severity capability.
Installation Category
Main circuit (including under-voltage release coil) is Category Ⅳ; control and auxiliary circuits are Category Ⅲ.
Installation & Protection
Vertical inclination limit of 5°. Protection class: IP30, IP40 (installed in cabinet compartment with door frames and organic glass covers).
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 ensures stable and consistent final contact pressure for each phase, optimizing 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 cabinet set.
-
It can be installed with bottom incoming lines and supports horizontal and vertical wiring methods.
-
Intelligent controller, with multiple protection functions, can realize selective protection.
