RDQ3CM series intelligent dual power auto transfer switch (brief as ATS) suitable for emergency power supply system with rated AC voltage 400V, 50/60Hz. When one power source fault, can auto interchange from main power to backup power, no need manual operation, to protect the power supply stability. Mainly apply to the important place which not allow power cutoff such as Hospital, shopping mall, bank, chemical industry, metallurgy, high building, military facilities and fire-fighting etc.
Product Structure
RDQ3CM series intelligent ATS comprised with two 3P or 4P MCCB and its accessories (Aux. contact,Alarm contact), Mechanical interlocking transmission mechanism, intelligent controller etc. Have two constructions of integral and split type. Integral type is controller and executive unit installed at a same base; Split type is controller installed on the panel and the executive unit installed on the base inside the panel box, a 2m length signal cable connecting the controller with the executive unit.
ABE 3 pole mccb breaker types is one of products developed and manufactured by adopting international advanced technology. MCCB is supplied with rated insulating voltage 550V and 800V and used for circuit of AC 50/60Hz, rated operating voltage AC 400V(or below), rated operating current up to 630A for infrequent changing over and starting of the motors. The electrical moulded case circuit breaker MCCB conforms to IEC60947-2 standard.
ABE/ABS moulded case circuit breakeris suitable for industrial or commercial power and lighting with AC50/ 60Hz, rated working voltage up to AC600V/DC250V, rated current up to 630A. Its a kind of economical breaker with the characters of stable and reliable function, beautiful appearance, small size and long life. It can be used for conversion of line and infrequent starting motor. It can also be attached to ins all the accessories which have protection function for avoiding loss of voltage, undervoltage.
