YSDM1E with residual current protection molded case circuit breaker ( hereinafter referred breaker ) , rated insulation voltage is 800V, suitable for AC 50Hz, rated working voltage 400V and below, rated current up to 630A of circuit for frequency converter and the motor does not infrequent start with . Breaker with overload, short circuit and under voltage protection function, can protect the circuit and power supply equipment from damage , but also can not detect overcurrent protection ground fault may cause long-term fire danger exists to provide protection.
● The circuit breaker according to its rated ultimate short-circuit breaking capacity (Icu) level , is divided into M -type ( high breaking type ), H -type ( high breaking type ) II . The circuit breaker has small size , high breaking arcing short , anti- vibration characteristics.
● The circuit breaker can be installed vertically ( ie, vertical loading ) , can be installed horizontally ( ie, transverse) .
● The circuit breaker can not be poured into the line , which allows only the power cord 1,3,5 , 2,4,6 then load line .
● The circuit breakers for isolation , symbols marked .
● The circuit breaker performs the following standards:
Breaker IEC60947-2 and GB14048.2 voltage circuit breakers and residual current protection with Appendix B of
IEC60947-4 and GB14048.4 contactors and motor starters
IEC60947-5.1 and GB14048.5 Electromechanical control circuit devices
● installation site altitude of 2000m and below;
● The ambient temperature is not higher than +40 ℃ and no less than -5 ℃;, and 24-hour average does not exceed 35 ℃ (excluding special orders);
● installation site relative humidity of air at a maximum temperature of 40 ℃, less than 50%; at lower temperatures, higher relative humidity, the wettest month of the monthly average minimum temperature does not exceed +25 ℃, the monthly the average maximum relative humidity less than 90%, taking into account the temperature changes on the surface of condensation;
● Pollution levels for three;
● Installation category for the main circuit breaker Ⅲ, not connected to the auxiliary circuits and control circuits of the main circuit, installation category Ⅱ;
● In the absence of explosive under medium and medium without enough to corrode metal and damage the insulation of gas and conductive dust place;
● In the absence of rain and snow;
● breaker should the product manual installation.
