Pollution degree: Level 3. Installation Category: Main circuit Category Ⅳ; control/auxiliary circuits Category Ⅲ.
Vertical inclination shall not exceed 5°. Protection class requirements: IP30, IP40 (with compartment door frames and organic glass covers).
Service category: B
Product Features
-
1
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.
-
2
The advanced arc-extinguishing system and protective cover ensure "zero flying arc", making the product more secure.
-
3
The circuit breaker is operated for energy storage by the energy-storage mechanism, with a fast closing speed.
-
4
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.
-
5
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.
-
6
It can be installed with bottom incoming lines and has horizontal and vertical wiring methods.
-
7
Intelligent controller, with multiple protection functions, can realize selective protection.
