First, the scope

YDM1 series molded case circuit breaker ( CM1 MCCB ), is adopting international advanced design and manufacturing technology research and development of new circuit breakers. Its rated insulation voltage is 690V, suitable for AC 50Hz, rated working voltage 400V and below, rated current 800A and below the circuit for frequency conversion and infrequent start motor used, the circuit breaker with overload, short circuit and undervoltage protection means to protect the circuit and power equipment from damage.
CM1 MCCB its rated limit short-circuit breaking capacity (lcu) level is divided into: C type (economy), L-type (standard), M-type (high breaking type), H type (high breaking type) four categories. CM1 molded case circuit breaker has small size, high breaking, short flying fox, anti-vibration and other characteristics, is ideal for land and marine use.
The molded case circuit breakers can be installed vertically (ie, vertical loading), it can also be installed horizontally (ie horizontal installation).
The product complies with IEC60947-2 and GB14048.2 standards.

Second, model and specification


Note:
1. handle direct operation no code, rotating operation in Z, electrically operated with P expressed;
2. only do isolated without tripping the circuit breaker to 000 means;
3. Motor protection circuit breaker 2, said power distribution with no code;
The four-pole circuit breaker neutral pole (N pole) structure code;
Type A: N pole not installed overcurrent tripping element, and N pole is always connected not with the other three poles combined points;
Type B: N pole not installed overcurrent tripping element, and the N pole and the other three poles combined points;
Type C: N pole installed current trip element, and the N pole and the other three poles combined points;
Type D: N pole installed current trip element, and N pole is always connected not with the other three poles combined points;

Third, the application environment

■ altitude of two thousand meters and below
■ ambient temperature is not higher than the positive forty degrees Celsius (for marine products is positive forty-five degrees Celsius), not less than minus five degrees Celsius.
■ able to withstand the impact of moist air;
■ can tolerate salt spray, impact of oil pollution;
■ can withstand the impact of mold;
■ able to withstand the effects of nuclear radiation;
■ The maximum angle of inclination of five past ten p.m. degree;
■ to work reliably in normal vibrations when subjected to the ship;
■ In case of an earthquake by (4g) can work reliably;
■ In the absence of explosive medium, the medium does not enough to corrode metal and damage the insulation of gas and conductive dust areas can work reliably;
■ In the absence of rain and snow erosion place to work reliably;
