1, uses CM1 series molded case circuit breakers rated insulation voltage of 800V (CM1-63 to 500V), suitable for AC 50HZ, rated working voltage 690V and below (CM1-63 to 400V), rated current up to 800A of circuit for frequency conversion and motor are not infrequent start. Circuit breaker with overload, short circuit and under-voltage protection function, can protect the circuit and power equipment from damage. Breaker according to its rated limit short-circuit breaking capacity (Icu) level, is divided into C type (basic type), L-type (standard), M-type (high breaking type), H type (high breaking type) four categories. Breaker can be installed vertically or horizontally installed. The circuit breaker has small size, high breaking, short arc (part of the specification is zero arcing), with isolated, anti-vibration characteristics, and by the nuclear industry conditions (1E-level) test test and ship condition is domestic products only can be used for nuclear industrial base product, it is ideal for land and marine use. 2. Perform standard product complies with IEC60947-2 (1995), GB14048.2 "low voltage circuit breakers" standard. 3. Conditions altitude does not exceed 2000m; maximum angle of inclination of 22.5 °; ambient temperature is not higher than + 40 ° C (for marine products to + 45 ° C) and no less than -5 ° C; can tolerate moist air , salt spray, mist, mold, the effects of nuclear radiation; work reliably when subjected to normal vibration of the ship; work reliably in the case by the earthquake (4g); in the absence of explosive medium, the medium does not enough to corrode metal and damage the insulation of gas and conductive dust place; in the absence of rain and snow. Currently the products are: CM1-63 three poles, four poles; CM1-100 two-pole, three poles, four poles; CM1-160 three poles, four poles; CM1-225 two-pole, three poles, four poles; CM1- 400 three poles, four poles; CM1-630 three poles, four poles;.
