Moulded Case Circuit Breakers

Description

RDM1 series molded case circuit breaker is suitable for the circuit of AC *0/*0Hz, rated current **0A, rated operating voltage **0V or less. The series circuit breaker, in the distribution network, can be used for distributing the energy or electricity and protecting the circuit and power device against overload, short-circuit and under-voltage. The circuit breaker with the frame rated current **0A or less can be used for protecting motors and starting motors non-frequently. Under normal conditions, it can also be used for making and breaking circuit frequently. Comply with demands of the folloing standards:IEC****7 and GB****8.2 Normal conditions of operation, installation and transportation: ***** ambinent termperture is between *5 degree and **0 degree 2.Altitude of installation can&#**9;t exceed ***0m ***** relative humidity of atmosphere is under *0% when the temperature kept under **0 degree.Higher relative humidity can be permitted at lower tempertures. Normal conditions of installation: ***** place of installation should not have shock and impact of rain and snow, the upper terminal connects to the power side, and the other to overload side, make sure that angle any direction is not more than 5 angle. ***** type of main circuit 3.Pollution grade:3, Auxiliary circui and controlling circuit:2 ***** outer magnetic field around the breaker is not more than five times of the grounds magnetic field in any direction
