Type : NFB-□S(a) Type
Low Capacity Series (30AF ~ 225AF)
▷ Targets One-Class higher Breaking Performance
― Actualized the highest breaking capacity in same class with the highest rated breaking capacity of 25kA (AC 460V standard).
▷ Interchangeable Internal Accessory (User-Free)
― Auxiliary Cover can be open/close, so that user can easily attach accessories.
▷ Unification of main dimensions
― Standardized panel design and production by the unification of the Height of Terminal Block (24mm) and the Height of Name Plate (60mm).
High Capacity Series (400AF ~ 1,200AF)
▷ Targets One-Class higher Breaking Performance
― Actualized the highest breaking capacity in same class with the highest rated breaking capacity of 65kA (AC 460V standard).
▷ Perfect compatibility
― There is no inconvenience in applying new products to switchboard because the frame size is same as other company’s.
▷ Interchangeable Internal Accessory (User-Free)
― Auxiliary Cover can be open/close, so that user can easily attach accessories.
▷ Convenient operation
― Production of 4 Pole and supplying External Operation Handle as a standard part
