1 scope of application
CM1 series plastic shell type circuit breaker ( hereinafter referred to as the circuit breaker ), the company adopts the international advanced design, manufacturing technology, developed a new type of breaker. The rated voltage of 800V, applicable to the exchange of 50Hz, rated voltage of 690V and below, ( CM1-63 to 400V ), rated current to 800A circuit for frequency conversion and motor protection ( CM1-800 motor protection type) with. Circuit breaker with overload, short circuit and under voltage protection function, can protect the circuit and power equipment from damage.
Circuit breaker according to its rated ultimate short-circuit breaking capacity ( Icu ) level, classified as type C ( basic), type L ( standard), M ( higher breaking type), type H ( high breaking type) four class. The circuit breaker has the advantages of small volume, high, breaking arc short (partial specifications of zero arcing ), vibration resistance and other characteristics, and through the nuclear industry condition ( 1E ) test and shipping conditions of the test, becoming the domestic products only can be used in the nuclear industry base products, more land and marine use ideal product.
The circuit breaker may be mounted vertically ( i.e. arranged vertically ), can also be installed on the level ( i.e., transverse mounting ).
The circuit breaker with isolation function, the corresponding symbol:".
Circuit breaker with IEC60947-2, GB14048.2 standard.
The circuit breaker by national mandatory product certification mark" CCC" and" TUV" in Germany ( Rhine) Company" CE" certification, as " China famous brand" products.
2 work environment
The circuit breaker may be in the ambient air temperature of - 5 DEG C to 40 DEG C under operating conditions ( greater than + 40 C to + 60 C derating use);
The elevation and the following 2000m;
The location of the installation of the air relative humidity at the highest temperature of + 40 C when not more than 50%, at lower temperatures can have a higher relative humidity, for example 20 degrees up to 90%. Due to temperature change occasionally produced gel should take special measures;
Pollution grade 3;
The main circuit and the circuit breaker undervoltage tripper mounted category III, the remaining auxiliary circuit, control circuit for II mounting classes;
Circuit breakers for electromagnetic environment of A;
Circuit breaker can tolerate humid air, salt fog, mist, mold, nuclear industry environment;
A circuit breaker mounting maximum inclination as - 22.5 deg;
Circuit breaker under the ships normal vibration can reliably work;
Circuit breaker under seismic conditions ( 4G ) can reliably work;
The breaker should be installed in no danger of explosion and no conductive dust, non-metal corrosion and damage to the insulation;
The breaker should be installed in the absence of snow or rain.
