1 scope of application
RZMM1 series moulded case circuit breaker (hereinafter referred to as circuit breaker), is the company with one of the new circuit breaker design, advanced manufacturing technology, the development of international development. Rated insulation voltage of 800V, applicable to AC 50Hz, rated voltage 690V and below, (RZM1400V), circuit of rated current to 800A in not frequently switch and motor protection (CM1-800 no motor protection type) with. Circuit breaker with overload, short circuit and under voltage protection function, can protect the circuit and the power equipment is not damaged.
Circuit breaker according to the rated ultimate short-circuit breaking capacity (Icu) level, classified as type C (basic), L type (standard type), M type (high breaking type), H type (high breaking type) four. The circuit breaker has the advantages of small size, high breaking arc, short (some specifications of zero arc), anti vibration, and by the nuclear industry (1E) test and the condition of the ship, to become the domestic products can only used for nuclear industry base products, is the ideal product of terrestrial and marine ships use.
The circuit breaker can be installed vertically (i.e. vertically installed), can also be installed on the level (i.e., transverse loading).
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 the German "TUV" (Rhine) Company "CE" certification, as "China famous brand" products.
