1. Purpose? 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. Implementation of standards? Product complies with IEC60947-2 (1995), GB14048.2 "low voltage circuit breakers" standard. 3. Conditions altitude does not exceed 2000m;? The 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;? Capability Affected moist air, salt spray, mist, mold, nuclear radiation;? can work reliably when subjected to normal vibration ship; work reliably in the case by the earthquake (4g);? In the absence of explosive medium, and medium without enough to corrode metal and damage the insulation of gas and conductive dust areas;? In the absence of rain and snow. ?
