1. Application and range of application
The NF-CS series plastic outer covering type circuit breaker (hereafter refers to as circuit breaker), is this company uses the international advanced design, one of the technique of manufacture development, development new circuit breakers. Its fixed isolation voltage is 690V, is suitable in exchanges 50Hz, fixed working voltage 400V and below.Rated current to 800A circuit as frequent changeover gum less frequent motor starter. The Circuit breaker with overload, short circuit protection device, and less voltage protection circuit and power equipment are not damaged.
