NBSe NF400-CS MCCB mold case circuit breaker, New Technology 3 Pole Circuit Breaker NF 400A MCCB
MCCB
It is a mechanical switching device that can connect, load and break the current under the normal circuit and can connect, load and break the current within a period of time under the unnormal circuit.
General
Advanced design,reliable performance,high technical guid line;elegant appearance, small bulk. It adopts micro-electronic technology, and has intelligent control function; complete series are zero arcintg.
1) The products conforms to GB14048.2,IEC60497-2 standards.
2) Equipment with the protection devices.
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.
